Hi,
I have had a similar issue in the past. I ended up giving up using different cards. I found that more similar cards were better. They did not seem to work correctly, I believe that if the level of hardware offload was different they had problems (as expected I suppose). Communication speeds, hardware offload and packet sizes can all cause issues. Is the Broadcom card one that supports hardware offload in linux?

This might be a bit of a stretch...

I was wondering if anyone on the list is using channel bonding with
dissimilar NIC's.  In the past I've always had dual-port Intel E1000's
which just work (on cisco catalyst switches).

I'm trying to get two single channel cards going, a broadcom and an
Intel E1000, and it dosn't appear to load balance the outbount traffic,
and the switch dosn't recognise the pair as an etherchannel pair.
(Etherchannel is the cisco name for channel bonding)

Google hasn't been much help on this one.. :-)

Cheers, Me.
