Hi,

I made "Ethernet hardawre flow control support" patch for NetBSD 1.6.2
(Currently, for sip, gsip, bge(UNTESTED) only).

This patch adds IEEE 802.3x flow control feature to NetBSD 1.6.2.
By applying this patch, the following things become possible.

a. If media is "auto", Perform an auto-negotiation also about a flow
control, and it performs a flow control based on the result of an
auto-negotiation. Result of a negotiation can check by ifconfig.

b. If media is not "auto", it can specify from ifconfig whether a flow
control is performed. Moreover, the method of a flow control(only
PAUSE transmission, only PAUSE reception, both) can also be specified
clearly if the device suppoted.
