[dpdk-dev] [PATCH] net/bnx2x: fix Rx mode configuration

[Rasesh Mody]

Check if promisc mode was set when setting allmulti mode and visa-versa.
Introduced BNX2X_RX_MODE_ALLMULTI_PROMISC for the same. If check is
absent the filter configuration gets over written.
Fixes: 540a211084a7 ("bnx2x: driver core")
Fixes: 5dbc53d7e5a2 ("net/bnx2x: restrict Rx mask flags sent to the PF")
