2015-11-20net: ethernet: add driver for Aurora VLSI NB8800 Ethernet controllerMåns Rullgård6-0/+1891
This adds a driver for the Aurora VLSI NB8800 Ethernet controller. It is an almost complete rewrite of a driver originally found in a Sigma Designs 2.6.22 tree. Signed-off-by: Mans Rullgard <mans@mansr.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-11-20net: tulip: turn compile-time warning into dev_warn()Arnd Bergmann2-3/+8
The tulip driver causes annoying build-time warnings for allmodconfig builds for all recent architectures: dec/tulip/winbond-840.c:910:2: warning: #warning Processor architecture undefined dec/tulip/tulip_core.c:101:2: warning: #warning Processor architecture undefined! This is the last remaining warning for arm64, and I'd like to get rid of it. We don't really know the cache line size, architecturally it would be at least 16 bytes, but all implementations I found have 64 or 128 bytes. Configuring tulip for 32-byte lines as we do on ARM32 seems to be the safe but slow default, and nobody who cares about performance these days would use a tulip chip anyway, so we can just use that. To save the next person the job of trying to find out what this is for and picking a default for their architecture just to kill off the warning, I'm now removing the preprocessor #warning and turning it into a pr_warn or dev_warn that prints the equivalent information when the driver gets loaded.

2015-11-19ravb: fix WARNING in __free_irq()Sergei Shtylyov1-2/+4
When the R8A7795 support was added to the driver, little attention was paid to the ravb_open() error path: free_irq() for the EMAC interrupt was called uncoditionally, unlike request_irq(), and in a wrong order as well... As a result, on the R-Car gen2 SoCs I started getting the following in case of a device opening error: WARNING: CPU: 0 PID: 1 at kernel/irq/manage.c:1448 __free_irq+0x8c/0x228() Trying to free already-free IRQ 0 Modules linked in: CPU: 0 PID: 1 Comm: swapper/0 Not tainted 4.4.0-rc1-dirty #1005 Hardware name: Generic R8A7791 (Flattened Device Tree) Backtrace: [<c0013818>] (dump_backtrace) from [<c00139b4>] (show_stack+0x18/0x1c) r6:c063cdd6 r5:00000009 r4:00000000 r3:00204140 [<c001399c>] (show_stack) from [<c022a578>] (dump_stack+0x74/0x90) [<c022a504>] (dump_stack) from [<c0025f04>] (warn_slowpath_common+0x8c/0xb8) r4:ef04fd38 r3:c0714770 [<c0025e78>] (warn_slowpath_common) from [<c0025fd4>] (warn_slowpath_fmt+0x38/0x40) r8:ee8ad800 r7:ef0030a0 r6:00000000 r5:00000000 r4:ef003040 [<c0025fa0>] (warn_slowpath_fmt) from [<c0064cc0>] (__free_irq+0x8c/0x228) r3:00000000 r2:c063ce9f [<c0064c34>] (__free_irq) from [<c0064ecc>] (free_irq+0x70/0xa4) r10:0000016b r8:00000000 r7:00000000 r6:ee8ad800 r5:00000000 r4:ef003040 [<c0064e5c>] (free_irq) from [<c033472c>] (ravb_open+0x224/0x274) r7:fffffffe r6:00000000 r5:fffffffe r4:ee8ad800 [<c0334508>] (ravb_open) from [<c041ac78>] (__dev_open+0x84/0x104) r7:ee8ad830 r6:c0566334 r5:00000000 r4:ee8ad800 [<c041abf4>] (__dev_open) from [<c041af08>] (__dev_change_flags+0x94/0x13c) r7:00001002 r6:00000001 r5:00001003 r4:ee8ad800 [<c041ae74>] (__dev_change_flags) from [<c041afe8>] (dev_change_flags+0x20/0x50) r7:c072e6e0 r6:00000138 r5:00001002 r4:ee8ad800 [<c041afc8>] (dev_change_flags) from [<c06ec06c>] (ip_auto_config+0x174/0xfb8) r8:00001002 r7:c072e6e0 r6:c0703344 r5:00000001 r4:ee8ad800 r3:00000101 [<c06ebef8>] (ip_auto_config) from [<c000a810>] (do_one_initcall+0x100/0x1cc) r10:c06fb83c r9:00000000 r8:c06ebef8 r7:c0736000 r6:c0710918 r5:c0710918 r4:ef2f8f80 [<c000a710>] (do_one_initcall) from [<c06ccddc>] (kernel_init_freeable+0x11c/0x1 ec) r10:c06fb83c r9:00000000 r8:0000009a r7:c0736000 r6:c0706bf0 r5:c06fb834 r4:00000007 [<c06cccc0>] (kernel_init_freeable) from [<c0514c54>] (kernel_init+0x14/0xec) r10:00000000 r8:00000000 r7:00000000 r6:00000000 r5:c0514c40 r4:c0736000 [<c0514c40>] (kernel_init) from [<c0010458>] (ret_from_fork+0x14/0x3c) r4:00000000 r3:ef04e000 Fix up the free_irq() call order and add a new label on the error path.

This patch adds the PCI device ID (0xe0a1) and alx_pci_tbl entry for the Killer E2400 Ethernet controller, modeled after the Killer E2200 controller support (0xe091) already present in the alx driver. This patch was originally authored by Ben Pope, but it got held up by issues in the commit message, so I'm resubmitting it on his behalf. I've extensively used a kernel with this patch on a System76 serw9 laptop and am quite confident it works well (at least on the hardware I have available for testing). Note that as a favor to System76, Ubuntu has been carrying this as a sauce patch in their 4.2 based Wily kernel, which presumably has given it real-world testing on other E2400 equipped hardware (I don't know of any Ubuntu kernel bugs filed about it): https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1498633 Signed-off-by: Jason Gerard DeRose <jason@system76.com> Signed-off-by: Ben Pope <benpope81@gmail.com> Signed-off-by: David S.

It's safe to ignore the new skb in the ipvlan_xmit_* functions, because they call ipvlan_rcv_frame with local == true, so that dev_forward_skb is called and always takes ownership of the skb.

2015-11-17via-velocity: unconditionally drop frames with bad l2 lengthTimo Teräs1-21/+3
By default the driver allowed incorrect frames to be received. What is worse the code does not handle very short frames correctly. The FCS length is unconditionally subtracted, and the underflow can cause skb_put to be called with large number after implicit cast to unsigned. And indeed, an skb_over_panic() was observed with via-velocity. This removes the module parameter as it does not work in it's current state, and should be implemented via NETIF_F_RXALL if needed.

Add support for IP1000A chips to dl2k driver. IP1000A chip looks like a TC9020 with integrated PHY. This allows IP1000A chips to work reliably because the ipg driver is buggy - it loses packets under load and then completely stops transmitting data. Tested with Asus NX1101 v2.0 at 10, 100 and 1000Mbps: vendor=0x13f0 device=0x1023 (rev 0x41) subsystem vendor=0x1043 device=0x8180 MAC address registers access needed to be changed from 8-bit to 16-bit because 8-bit does not work on IP1000A. 8-bit access is not even allowed in the TC9020 datasheet (although it worked). 16-bit access works on both. Tested that it does not break D-Link DGE-550T (DL-2000 chip, probably a rebranded TC9020): vendor=0x1186 device=0x4000 (rev 0x0c) subsystem vendor=0x1186 device=0x4000 Signed-off-by: Ondrej Zary <linux@rainbow-software.org> Reviewed-by: Andy Shevchenko <andy.shevchenko@gmail.com> Signed-off-by: David S.

2015-11-16ath10k: poll HTT send completion when CE 5 is unusedRajkumar Manoharan1-1/+12
commit a70587b3389a ("ath10k: configure copy engine 5 for HTT messages") moved send completion polling under HTT Rx (CE 5) service routine. For QCA6174 based devices copy engine 1 (CE 1) is used for HTT Rx instead of CE 5. So send completion never be called. This is causing "failed to transmit packet, dropping: -105" errors. Fix this by processing send completion from CE 1 service routine instead of CE 5.

Commit 77a993942 "phy/at8031: enable at8031 to work on interrupt mode" added interrupt support for the 8031 PHY but left out the other two chips supported by this driver. This patch sets the .ack_interrupt and .config_intr functions for the 8030 and 8035 drivers as well.

2015-11-16net/mlx4_core: Fix sleeping while holding spinlock at rem_slave_countersEran Ben Elisha1-12/+27
When cleaning slave's counter resources, we hold a spinlock that protects the slave's counters list. As part of the clean, we call __mlx4_clear_if_stat which calls mlx4_alloc_cmd_mailbox which is a sleepable function. In order to fix this issue, hold the spinlock, and copy all counter indices into a temporary array, and release the spinlock. Afterwards, iterate over this array and free every counter. Repeat this scenario until the original list is empty (a new counter might have been added while releasing the counters from the temporary array).

2015-11-16net/mlx5e: Added self loopback preventionTariq Toukan1-0/+48
Prevent outgoing multicast frames from looping back to the RX queue. By introducing new HW capability self_lb_en_modifiable, which indicates the support to modify self_lb_en bit in modify_tir command. When this capability is set we can prevent TIRs from sending back loopback multicast traffic to their own RQs, by "refreshing TIRs" with modify_tir command, on every time new channels (SQs/RQs) are created at device open. This is needed since TIRs are static and only allocated once on driver load, and the loopback decision is under their responsibility. Fixes issues of the kind: "IPv6: eth2: IPv6 duplicate address fe80::e61d:2dff:fe5c:f2e9 detected!" The issue is seen since the IPv6 solicitations multicast messages are loopedback and the network stack thinks they are coming from another host.
