      cxgb4: drop __GFP_NOFAIL allocation · f72f116a
      由 Michal Hocko 提交于 
      set_filter_wr is requesting __GFP_NOFAIL allocation although it can return
ENOMEM without any problems obviously (t4_l2t_set_switching does that
already).  So the non-failing requirement is too strong without any
obvious reason.  Drop __GFP_NOFAIL and reorganize the code to have the
failure paths easier.

The same applies to _c4iw_write_mem_dma_aligned which uses __GFP_NOFAIL
and then checks the return value and returns -ENOMEM on failure.  This
doesn't make any sense what so ever.  Either the allocation cannot fail or
it can.

del_filter_wr seems to be safe as well because the filter entry is not
marked as pending and the return value is propagated up the stack up to
c4iw_destroy_listen.

      ethtool: Support for configurable RSS hash function · 892311f6
      由 Eyal Perry 提交于 
      This patch extends the set/get_rxfh ethtool-options for getting or
setting the RSS hash function.

It modifies drivers implementation of set/get_rxfh accordingly.

This change also delegates the responsibility of checking whether a
modification to a certain RX flow hash parameter is supported to the
driver implementation of set_rxfh.

User-kernel API is done through the new hfunc bitmask field in the
ethtool_rxfh struct. A bit set in the hfunc field is corresponding to an
index in the new string-set ETH_SS_RSS_HASH_FUNCS.

Got approval from most of the relevant driver maintainers that their
driver is using Toeplitz, and for the few that didn't answered, also
assumed it is Toeplitz.

      cxgb4/cxgb4vf/csiostor: Add T4/T5 PCI ID Table · 3fedeab1
      由 Hariprasad Shenai 提交于 
      Add a new file t4_pci_id_tbl.h that contains T4/T5 PCI ID Table so that for all
drivers that uses T4/T5 PCI functions changes can be done in one place.

checkpatch.pl script reports following error, which if tried to fix ends up in
compilation error.
