From: Vadim Lomovtsev Date: Fri, 30 Mar 2018 11:59:52 +0000 (-0700) Subject: net: thunderx: add workqueue control structures for handle ndo_set_rx_mode request X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=1b6d55f23948df5ea2b9f59b766bed91fb609b99;p=openwrt%2Fstaging%2Fblogic.git net: thunderx: add workqueue control structures for handle ndo_set_rx_mode request The kernel calls ndo_set_rx_mode() callback from atomic context which causes messaging timeouts between VF and PF (as they’re implemented via MSIx). So in order to handle ndo_set_rx_mode() we need to get rid of it. This commit implements necessary workqueue related structures to let VF queue kernel request processing in non-atomic context later.
