net/mlx5_core: Fix trimming down IRQ number

2016-01-31T19:25:52+00:00

[ Upstream commit 0b6e26ce89391327d955a756a7823272238eb867 ] With several ConnectX-4 cards installed on a server, one may receive irqn > 255 from the kernel API, which we mistakenly trim to 8bit. This causes EQ creation failure with the following stack trace: [] dump_stack+0x48/0x64 [] __setup_irq+0x3a1/0x4f0 [] request_threaded_irq+0x120/0x180 [] ? mlx5_eq_int+0x450/0x450 [mlx5_core] [] mlx5_create_map_eq+0x1e4/0x2b0 [mlx5_core] [] alloc_comp_eqs+0xb1/0x180 [mlx5_core] [] mlx5_dev_init+0x5e9/0x6e0 [mlx5_core] [] init_one+0x99/0x1c0 [mlx5_core] [] local_pci_probe+0x4c/0xa0 Fixing it by changing of the irqn type from u8 to unsigned int to support values > 255 Fixes: 61d0e73e0a5a ('net/mlx5_core: Use the the real irqn in eq->irqn') Reported-by: Jiri Pirko Signed-off-by: Doron Tsur Signed-off-by: Matan Barak Signed-off-by: David S.

dwc_eth_qos: Fix dma address for multi-fragment skbs

[ Upstream commit d461873272169a3fc3a8d155d7b1c92e9d97b419 ] The offset inside the fragment was not used for the dma address and silent data corruption resulted because TSO makes the checksum match.

gianfar: Don't enable RX Filer if not supported

2016-01-23T04:55:50+00:00

[ Upstream commit 7bff47da1ee23d00d1257905f2944c29594f799d ] After commit 15bf176db1fb ("gianfar: Don't enable the Filer w/o the Parser"), 'TSEC' model controllers (for example as seen on MPC8541E) always have 8 bytes stripped from the front of received frames. Only 'eTSEC' gianfar controllers have the RX Filer capability (amongst other enhancements). Previously this was treated as always enabled for both 'TSEC' and 'eTSEC' controllers. In commit 15bf176db1fb ("gianfar: Don't enable the Filer w/o the Parser") a subtle change was made to the setting of 'uses_rxfcb' to effectively always set it (since 'rx_filer_enable' was always true). This had the side-effect of always stripping 8 bytes from the front of received frames on 'TSEC' type controllers. We now only enable the RX Filer capability on controller types that support it, thereby avoiding the issue for 'TSEC' type controllers.

net: qca_spi: fix transmit queue timeout handling

2016-01-23T04:55:45+00:00

[ Upstream commit ed7d42e24effbd3681e909711a7a2119a85e9217 ] In case of a tx queue timeout every transmit is blocked until the QCA7000 resets himself and triggers a sync which makes the driver flushs the tx ring. So avoid this blocking situation by triggering the sync immediately after the timeout. Waking the queue doesn't make sense in this situation.

atl1c: Improve driver not to do order 4 GFP_ATOMIC allocation

2016-01-23T04:55:44+00:00

[ Upstream commit f2a3771ae8aca879c32336c76ad05a017629bae2 ] atl1c driver is doing order-4 allocation with GFP_ATOMIC priority. That often breaks networking after resume. Switch to GFP_KERNEL. Still not ideal, but should be significantly better. atl1c_setup_ring_resources() is called from .open() function, and already uses GFP_KERNEL, so this change is safe.

[ Upstream commit 7750130d93decff06120df0d8ea024ff8a038a21 ] In some cases the crash is caused by nicvf_remove() being called from outside.
