Date: Wed, 12 Nov 2008 10:36:33 +0100 From: Jesper Dangaard Brouer <jdb@...x.dk> To: David Miller <davem@...emloft.net> Cc: jesper@...gh.cc, netdev@...r.kernel.org Subject: Re: NIU driver: Sun x8 Express Quad Gigabit Ethernet Adapter 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, ...)) -- Med venlig hilsen / Best regards Jesper Brouer ComX Networks A/S Linux Network developer Cand. Scient Datalog / MSc.
