>Description:
/usr/src/sys/dev/e1000/README mentions two switches that have link problems with Intel 82541/82547 controllers. I have multiple 82541PI controllers, sold as "PRO/1000 GT" cards, that exhibit the same behavior with Netgear GS105v3 switches (I tested two). More specifically, they take a very long time to auto-negotiate, and when they do, the media is 10BaseT. Manually setting media to something faster results in no carrier. Compiling the em driver with the "#define EM_MASTER_SLAVE   2" workaround fixes the problem, so I propose that the Netgear GS105v3 be added to the list of problem switches.
