Subject: Broadcom 5708 taking a few seconds to get link-up

Hi Michael,

I'm working on a system that has two on-board 5708's.  We've noticed 
that it takes about 3 seconds for the link to come up - is this 
considered normal?  I've tried this with the latest davem tree with 
similar results to older kernels/drivers.

# uname -r
2.6.24

# ethtool -i eth3
driver: bnx2
version: 1.7.3
firmware-version: 1.9.3
bus-info: 0000:42:00.0

# lspci -v

# ip link set eth3 up; mii-tool eth3; sleep 1; mii-tool eth3; sleep 1; 
mii-tool eth3; sleep 1; mii-tool eth3
eth3: no link
eth3: no link
eth3: no link
eth3: negotiated 100baseTx-FD, link ok

Other drivers I've tried - e1000 and tg3, get up in < 1 second.  I'm 
asking becuase any packet I try to transmit out this interface before 
link-up never gets out.

Thanks for any info,

-Brian
