i implemented netmap support (tx only) long ago, and found that the board is
uncapable of more than 2.5-3Mpps so there is not much of a point in using
netmap with it.

Hello @vmaffione
There is more details about you test with bnx2 module? In newer kernel versions, the performance issue still existing?
Thanks!
P.s: I have disposition to test. Here I have a unused machine with following nic:
02:00.0 Ethernet controller: Broadcom Limited NetXtreme II BCM5716 Gigabit Ethernet (rev 20)
02:00.1 Ethernet controller: Broadcom Limited NetXtreme II BCM5716 Gigabit Ethernet (rev 20)
from netmap.
Well, I never tested those actually. There is no native support for bnx2, so you are using the emulated adapter, which comes at reduced performance.
Patches for native bnx2 support are welcome.

@vmaffione but its possible to be done? There something in hardware that can be a no-go for netmap in bnx2? I know there is no native driver but afaik, this report is about a patch to support nativelly the bnx2 module, right?
Thanks!
from netmap.
Yes, it can be done, for instance following the recommendations in #264 , and the NIC documentation would probably help.
I read in this thread that someone tried to add support for bnx2, but we have no more information (is the code available ? , what's the status ?, etc.)
