bnxt_en: Add support for L2 rewrite
This patch adds support for packet edit offload of L2 fields (src mac &
dst mac, also referred as L2 rewrite). Only when the mask is fully exact
match for a field, the command is sent down to the adapter to offload
such a flow. Otherwise, an error is returned.
v2: Fix pointer alignment issue in bnxt_fill_l2_rewrite_fields() [MChan]
