Couple conflicts resolved here: 1) In the MACB driver, a bug fix to properly initialize the RX tail pointer properly overlapped with some changes to support variable sized rings. 2) In XGBE we had a "CONFIG_PM" --> "CONFIG_PM_SLEEP" fix overlapping with a reorganization of the driver to support ACPI, OF, as well as PCI variants of the chip. 3) In 'net' we had several probe error path bug fixes to the stmmac driver, meanwhile a lot of this code was cleaned up and reorganized in 'net-next'. 4) The cls_flower classifier obtained a helper function in 'net-next' called __fl_delete() and this overlapped with Daniel Borkamann's bug fix to use RCU for object destruction in 'net'. It also overlapped with Jiri's change to guard the rhashtable_remove_fast() call with a check against tc_skip_sw(). 5) In mlx4, a revert bug fix in 'net' overlapped with some unrelated changes in 'net-next'. 6) In geneve, a stale header pointer after pskb_expand_head() bug fix in 'net' overlapped with a large reorganization of the same code in 'net-next'. Since the 'net-next' code no longer had the bug in question, there was nothing to do other than to simply take the 'net-next' hunks. Signed-off-by: David S. Miller <davem@davemloft.net>
2016-11-30net: fec: cache statistics while device is downNikita Yushchenko2-4/+21
Execution 'ethtool -S' on fec device that is down causes OOPS on Vybrid board: Unhandled fault: external abort on non-linefetch (0x1008) at 0xe0898200 pgd = ddecc000 [e0898200] *pgd=9e406811, *pte=400d1653, *ppte=400d1453 Internal error: : 1008 [#1] SMP ARM ... Reason of OOPS is that fec_enet_get_ethtool_stats() accesses fec registers while IPG clock is stopped by PM. Fix that by caching statistics in fec_enet_private. Cache is initialized at device probe time, and updated at statistics request time if device is up, and also just before turning device off on down path. Additional locking is not needed, since cached statistics is accessed either before device is registered, or under rtnl_lock().

2016-11-27ptp: gianfar: Use high resolution frequency method.Ulrik De Bie1-8/+13
This patch depends on commit d8d263541913 ("ptp: Introduce a high resolution frequency adjustment method.") The gianfar devices offer a frequency resolution of about 0.46 ppb (depends on actual value of tmr_add, for the calculation assumed 0x80000000). This patch lets users of the device benefit from the increased frequency resolution when tuning the clock. Thanks to the rounding the maximum error between the requested frequency and the applied frequency will then be about 0.23 ppb. Tested on a v3.3.8 kernel on a real gianfar device. Verified compilation on net-next (currently at v4.9-rc5). Signed-off-by: Ulrik De Bie <ulrik.debie-os@e2big.org> Signed-off-by: David S. Miller <davem@davemloft.net>

There are only a handful of Freescale Ethernet drivers that don't actually build with COMPILE_TEST: * FEC, for which we would need to define a default register layout if no supported architecture is defined * UCC_GETH which depends on PowerPC cpm.h header (which could be moved to a generic location) * GIANFAR needs to depend on HAS_DMA to fix linking failures on some architectures (like m32r) We need to fix an unmet dependency to get there though: warning: (FSL_XGMAC_MDIO) selects OF_MDIO which has unmet direct dependencies (OF && PHYLIB) which would result in CONFIG_OF_MDIO=[ym] without CONFIG_OF to be set.

2016-11-16ptp_clock: Allow for it to be optionalNicolas Pitre1-1/+1
In order to break the hard dependency between the PTP clock subsystem and ethernet drivers capable of being clock providers, this patch provides simple PTP stub functions to allow linkage of those drivers into the kernel even when the PTP subsystem is configured out. Drivers must be ready to accept NULL from ptp_clock_register() in that case. And to make it possible for PTP to be configured out, the select statement in those driver's Kconfig menu entries is converted to the new "imply" statement. This way the PTP subsystem may have Kconfig dependencies of its own, such as POSIX_TIMERS, without having to make those ethernet drivers unavailable if POSIX timers are cconfigured out. And when support for POSIX timers is selected again then the default config option for PTP clock support will automatically be adjusted accordingly. The pch_gbe driver is a bit special as it relies on extra code in drivers/ptp/ptp_pch.c. Therefore we let the make process descend into drivers/ptp/ even if PTP_1588_CLOCK is unselected.

2016-10-13net: deprecate eth_change_mtu, remove usageJarod Wilson4-4/+0
With centralized MTU checking, there's nothing productive done by eth_change_mtu that isn't already done in dev_set_mtu, so mark it as deprecated and remove all usage of it in the kernel. All callers have been audited for calls to alloc_etherdev* or ether_setup directly, which means they all have a valid dev->min_mtu and dev->max_mtu. Now eth_change_mtu prints out a netdev_warn about being deprecated, for the benefit of out-of-tree drivers that might be utilizing it. Of note, dvb_net.c actually had dev->mtu = 4096, while using eth_change_mtu, meaning that if you ever tried changing it's mtu, you couldn't set it above 1500 anymore. It's now getting dev->max_mtu also set to 4096 to remedy that. v2: fix up lantiq_etop, missed breakage due to drive not compiling on x86 CC: netdev@vger.kernel.org Signed-off-by: Jarod Wilson <jarod@redhat.com> Signed-off-by: David S.
