bnx2x: multicasts in NPAR mode (d9c8f498) · Commits · 戴 / test

The chip was erroneously configured to accept all multicast frames in a normal (none-promisc) rx mode both on the RSS and on the FCoE L2 rings when in an NPAR mode. This caused packet duplication for every received multicast frame in this mode. Signed-off-by:
