X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=83eb5c5cff32681f3769f502cb5589c7d7509bfe;p=openwrt%2Fstaging%2Fblogic.git bnxt_en: Add software "missed_irqs" counter. To keep track of the number of times the workaround code for 57500 A0 has been triggered. This is a per NQ counter. Signed-off-by: Michael Chan Signed-off-by: David S.
