Subject: bnx2x: Do not call load/unload functionality from DCC
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=061bc702f6912b6e45b9aaf1c9bf2f8122406d47;p=openwrt%2Fstaging%2Fblogic.git

bnx2x: Do not call load/unload functionality from DCC

There is really no need to clear the MAC or the FW filtering rules - it was
added for completion, but caused race conditions with load/unload. Removing this
redundant code
