From: Jacob Keller Date: Fri, 14 Jul 2017 13:10:09 +0000 (-0400) Subject: i40e: move enabling icr0 into i40e_update_enable_itr X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=9254c0e34e4253c41fdcd4670b754506ce20d3eb;p=openwrt%2Fstaging%2Fblogic.git i40e: move enabling icr0 into i40e_update_enable_itr If we don't have MSI-X enabled, we handle interrupts on all icr0. This is a special case, so let's move the conditional into i40e_update_enable_itr() in order to make i40e_napi_poll easier to read about.
