src/sys/dev/pci/ixgbe: ixgbe.c ixgbe_common.c ixgbe_type.h
Log Message:
Count the number of link down events in the MAC using with LINK_DN_CNT.
- Add new event counter "link_dn_cnt" to count the number of link down
events in the MAC.
- The LINK_DN_CNT register (at 0x0403c) is described only in the
Denverton's datasheet, so use it only on ixgbe_mac_X550EM_a.
