[net-next, v3 00/11] add features to bnge

Hi,

This series adds ntuple filter, RSS context, and flow steering
support to bnge driver.
Patch 2 is a pure refactor (no functional change) that relocates the
filter and VNIC related code into the appropriate files. Patch 7 drops
the refcount usage from L2 filters, also with no functional change.
The subsequent patches then add the ethtool commands for configuring 
ntuple flows and RSS contexts.

Thanks,
Vikas

v2->v3:
   - Build fix.
   - Addressed comments from Sashiko

    Below Sashiko comments are not valid:
     Patch-8: 
                Comment under bnge_toeplitz().
                 Explanation: bnge_toeplitz() is not used for aRFS.
     Patch-9:
                Comment regarding bnge_clear_usr_fltrs().
                 Explanation:
                  Both bnge_clear_usr_fltrs() (only invoked while the
                  interface is down) and bnge_grxclsrule() execute
                  under the netdev instance lock, so they are
                  serialized and never touch the filter list at the 
                  same time.
      Patch-10: 
                Comment "Does this direct dereference of the MAC
                header need a linearization ...".
                 Explanation: ndo_rx_flow_steer runs on the RX path
                after eth_type_trans(), which already accesses and
                pulls the Ethernet header.

                Comment Related to bnge_cfg_ntp_filters().
                 Explanation:
                   bnge_cfg_ntp_filters() runs from bnge_sp_task(),
                   which holds the netdev instance lock while executing.
