Re: Question about tg3 and bnx2 driver suppliers

I'm trying to fix a problem with packet drops and frame errors (really
rxbds_empty and rx_discards (or rx_fw_discards depending on whether or
not its a tg3 supported chip or a bnx2 chip)). We have this happening
on pretty much all the RedHat 5.x systems we're running these drivers
on. In investigating what remedies to employ to fix this, I'm trying
to determine if new versions of this driver are supplied by Broadcom,
or by people within the Linux community so 
I can find the right place to ask questions about it. I'm pretty sure
this isn't the right list for these types of questions, but if someone
could tell me whether I should be contacting Broadcom directly, or the
name of some other Linux mailing list or forum that might help, I'd
appreciate it.

It _is_ the right place, dont worry ;)

One possible cause of packet drops is when softirqs are disabled for too
long periods, even if NIC has a big RX ring (check ethtool -g eth0)

We fixed one big offender some weeks ago : iptables -L

Fix is in commit 83723d60717f8da0f53f
