[src/trunk]: src/sys/dev/pci/ixgbe Sync with FreeBSD's ixv-1.5.17:

[msaitoh <msaitoh%NetBSD.org@localhost>]

details:   https://anonhg.NetBSD.org/src/rev/372bb28aebe1
branches:  trunk
changeset: 1000041:372bb28aebe1
user:      msaitoh <msaitoh%NetBSD.org@localhost>
date:      Tue Jul 02 07:20:07 2019 +0000

description:
Sync with FreeBSD's ixv-1.5.17:
 - When ixv_check_link() failed in the watchdog function, reset the interface.
 - Remove RXCSUM register modification in ixv_initialize_receive_units().
   It seems it's not required.
 - Remove some debug printf in ixv_print_debug_info().
 - Modify to match the newer NETMAP interface. No functional change.
