2020-05-08iwlwifi: pcie: skip fragmented receive buffersJohannes Berg2-6/+30
We don't really expect fragmented RBs, and don't seem to be seeing them in practice since that would've caused a crash. Nevertheless, we should be expecting the hardware to send them. Parse the flag indicating a fragmented buffer, but then discard it and any fragments thereof, at least for now. We need to do more work in the higher layers to properly deal with this, since we may not get "normal" firmware notifications that are fragmented, only RX, and then we need to put it back together and add the necessary API to report a chain of things to the higher layers, this doesn't fit into the struct iwl_rx_cmd_buffer today.

2020-05-08iwlwifi: mvm: don't transmit on unallocated queueJohannes Berg1-1/+11
We can currently end up transmitting on an unallocated queue, if the allocation fails. Stop doing that, by simply not transmitting. We don't have any better strategy here, unfortunately, but the previous commits make that much less likely.

2020-05-08iwlwifi: use longer queues for 256-BAJohannes Berg2-2/+2
When we have 256 block-ack support, we may need to be very fast to provide a lot of frames to the hardware to transmit, but that cannot be guaranteed. Use a longer queue size to have more time, and the next possible queue size is 1024 since it must be a power of two.

2020-05-08iwlwifi: pcie: gen2: use DMA pool for byte-count tablesJohannes Berg3-3/+28
Since the recent patch in this area, we no longer allocate 64k for a single queue, but only 1k, which still means a full page. Use a DMA pool to reduce this further, since we will have a lot of queues in a typical system that can share pages.

2020-05-08iwlwifi: mvm: attempt to allocate smaller queuesJohannes Berg1-8/+15
We currently attempt to allocate queues that are 512 entries long, but that requires 32 KiB memory, which may not be available, at least not contiguously. If we fail to allocate, attempt to use a smaller queue all the way down to 16 entries (which fit into a single page).

2020-05-08iwlwifi: pcie: allocate much smaller byte-count tableJohannes Berg2-12/+19
The hardware needs a byte-count table with the size of each frame on the queue to build A-MPDUs, but: * newer generation no longer have the duplicated space at the end, they can deal with the wrap properly - and we don't even fill the dup anyway * we have a maximum queue size of 512 right now and don't use the theoretical hardware maximum of 65536. Together, this reduces the byte count table DMA allocation from 64KiB (65536*2 + 64*2 rounded up) to 1 KiB (though that might be rounded up to a full 4 KiB page by the allocator, not sure it can share the allocations.)

Currently, bonding always returns NETDEV_TX_OK to its caller.

2020-05-08net: remove newlines in NL_SET_ERR_MSG_MODJacob Keller6-9/+84
The NL_SET_ERR_MSG_MOD macro is used to report a string describing an error message to userspace via the netlink extended ACK structure. It should not have a trailing newline. Add a cocci script which catches cases where the newline marker is present. Using this script, fix the handful of cases which accidentally included a trailing new line. I couldn't figure out a way to get a patch mode working, so this script only implements context, report, and org.

2020-05-08net: ethernet: ti: am65-cpsw-nuss: use of_platform_device_create() for mdioGrygorii Strashko2-6/+20
The MCU CPSW expected to populate only MDIO device, but follow up patches will add "compatible" property to the MCU CPSW CPTS node which will cause creation of CPTS device and MCU CPSW init failure. Hence, switch to use of_platform_device_create() instead of of_platform_populate() for MDIO device population. Signed-off-by: Grygorii Strashko <grygorii.strashko@ti.com> Signed-off-by: David S.

2020-05-08dpaa2-eth: create a function to flush the XDP fdsIoana Ciornei2-22/+46
Create an independent function that takes a particular frame queue and an array of frame descriptors and tries to enqueue them until it hits the maximum number fo retries. The same function will be used in the next patch also on the XDP_TX path. Also, create the dpaa2_eth_xdp_fds structure to incorporate the array of FDs as well as the number of FDs already populated.
