[dpdk-dev] [PATCH v2 13/34] net/bnxt: fetch SVIF information from the firmware

[Venkat Duvvuru <venkatkumar.duvvuru@broadcom.com>]

SVIF (source virtual interface) is used to represent a physical port,
physical function, or a virtual function. SVIF is compared during L2
context and exact match lookups in TX direction. SVIF is masked for
port information during L2 context and exact match lookup in RX direction.
Hence, driver needs this SVIF information to program L2 context and Exact
match tables.
