Hi DaveM
Before trying out the patch, I'll give you a small status on my
progress.
When using Sun's "nxge" driver everything works. Although this driver
is quite slow because it does not use the new TX qdisc scheme. I hacked
net/core/dev.c to avoid the qdisc TX code-path, and got an amazing
speedup, as I now can route 930 kpps (packets per sec).
I played a bit with the msglvl (debug log level) via:
ethtool -s eth2 msglvl 0x587
Enabling:
NETIF_MSG_TX_ERR
NETIF_MSG_TX_QUEUED
NETIF_MSG_TX_DONE
The thing I noticed is that it looks like the function niu_tx_work() is
never called... (it contains a niudbg(TX_DONE, ...))
