bnxt_en: Add support for ntuple filters added from ethtool.

Browse source

Add support for adding user defined ntuple TCP/UDP filters.  These
filters are similar to aRFS filters except that they don't get aged.
Source IP, destination IP, source port, or destination port can be
unspecifed as wildcard.  At least one of these tuples must be specifed.
If a tuple is specified, the full mask must be specified.

All ntuple related ethtool functions are now no longer compiled only
for CONFIG_RFS_ACCEL.
