Subject: net/bnx2x: restrict Rx mask flags sent to the PF
X-Git-Tag: spdx-start~5541

net/bnx2x: restrict Rx mask flags sent to the PF

Don't use bnx2x_fill_accept_flags() to fill the RX mask in the VF
since the PF only handles a subset of the existing flags.  now,
bnx2x_fill_accept_flags() can be static.

Fixes: 540a211084a7 ("bnx2x: driver core")
