SVN rev 214696 on 2010-11-02 22:48:52Z by yongari
MFC r213081,213225,213280:
r213081:
Always show asic/chip revision in device attach phase. There are
too many bge(4) controllers there and model name does not
necessarily match asic/chip revision. Relying on VPD string made
it hard to identify exact asic/chip revision so the first step to
debug bge(4) was getting exact asic/chip information with verbose
boot which may not be available on production server.
r213255:
Set the number of RX frames to receive after RX MBUF low watermark
has reached. This reduced number of dropped frames when
flow-control is enabled. Previously it dropped incoming frames once
RX MBUF low watermark has reached. The value used in MAC RX MBUF
low watermark is greater than or equal to 4 so receiving two more
RX frames should not be a problem.
Obtained from: OpenBSD
r213280:
After r207391, brgphy(4) passes resolved flow-control settings to
parent driver. Use that information to configure flow-control.
One drawback is there is no way to disable flow-control as we still
don't have proper way to not advertise RX/TX pause capability to
link partner. But I don't think it would cause severe problems and
users can selectively disable flow-control in switch port.
