Subject: 95fcoe: support bnx2fc
X-Git-Tag: 014~21
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f6783bee07d04f8d80c7c14bc0f1ceb7e9dade41;p=thirdparty%2Fdracut.git

95fcoe: support bnx2fc

To start bnx2fc, we need to run fipvlan only and not dcbtool.  DCBX is run
automatically in the hardware, but VLAN discovery needs to be started by
fipvlan.
