From: Jeffrey Huang Date: Sun, 27 Dec 2015 23:19:18 +0000 (-0500) Subject: bnxt_en: support hwrm_func_drv_unrgtr command X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=be58a0da1672391b246880450e990fe36d7ba24d;p=openwrt%2Fstaging%2Fblogic.git bnxt_en: support hwrm_func_drv_unrgtr command During remove_one, the driver should issue hwrm_func_drv_unrgtr command to inform firmware that this function has been unloaded. This is to let firmware keep track of driver present/absent state when driver is gracefully unloaded. A keep alive timer is needed later to keep track of driver state during abnormal shutdown.
