It's still driver-dependent though. If the driver didn't capture the
information, it doesn't matter if you look in dmesg, /proc, or
/var/log/syslog -- it ain't there :-)

[jack@localhost jack]$ sudo mii-tool
Password:
eth0: negotiated 100baseTx-FD flow-control, link ok
[jack@localhost jack]$ dmesg | grep eth0
divert: allocating divert_blk for eth0
eth0: Intel Corp. 82557/8/9 [Ethernet Pro 100], 00:02:B3:0A:E3:5C, IRQ
18.

[jcoates@jubjub jcoates]$ dmesg | grep eth0
eth0: Tigon3 [partno(BCM95701A10) rev 0105 PHY(5701)]
(PCIX:133MHz:64-bit) 10/100/1000BaseT Ethernet 00:06:5b:3f:1a:9a
eth0: Link is up at 100 Mbps, full duplex.
eth0: Flow control is off for TX and off for RX.
