To prevent lockup situations with full send queues when further interrupts fail to appear, the em(4) <http://www.openbsd.org/cgi-bin/man.cgi?query=em&manpath=OpenBSD%20Current&sektion=4&format=html> driver's start routine is triggered after the link status has been updated.
No longer attempt to enable MSI on 82571/82572 em(4) <http://www.openbsd.org/cgi-bin/man.cgi?query=em&manpath=OpenBSD%20Current&sektion=4&format=html> Gigabit ethernet controllers (to workaround "Byte Enables 2 and 3 Are Not Set" hardware bug).
