NAPI (aka RX Polling) for natsemi?

[Daniel Higgins]

hi all,
is there such a thing anywhere as a working patch to enable NAPI in the
natsemi driver? or is someone working on one?

so far i have found two non-working patches, which i tried to get to
work without success. one locks up the kernel, the other says "interrupt
while polling". any help with these would be appreciated.
the DP83815 (natsemi) are used a lot on embedded routers (soekris, wrap,
routerboard) and since they all use a geode processor which isn't all
that powerful, they get stuck in a livelock at around 50-60 mbits and
reboot shortly after due to the watchdog

here's the patches i found if that can help anyone:
http://gnumonks.org/ftp/pub/patches/natsemi-napi.patch    locks up the
kernel once it receives some packet (guessing it's stuck in polling mode.. )
http://www.spine-group.org/sources/natsemi.diff    has "interrupts while
polling" messages and the throughput drops off to zero

cc: me because i'm not subscribed

thanks for any help and pointers

It is bugzilla, not featurewishzilla. If some external patches
cause problem I suggest to contact their authors.
