ixgbe: Fix race condition where RX buffer could become corrupted.
There was a race condition in the reset path where the RX buffer could become corrupted during Fdir configuration.This is due to a HW bug.The fix right now is to lock the buffer while we do the fdir configuration.Since we were using similar workaround for another bug, I moved the existing code to a function and reused it.HW team also recommended that IXGBE_MAX_SECRX_POLL value be changed from 30 to 40.The erratum for this bug will be published in the next release 82599 Spec Update Signed-off-by: Atita Shirwaikar <atita.shirwaikar@intel.com> Acked-by: Peter P Waskiewicz Jr <peter.p.waskiewicz.jr@intel.com> Tested-by: Stephen Ko <stephen.s.ko@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
