Hi all
I'm using a tigon3 with 2.6.1 vanilla (lspci -vv and /proc/interrupts at the end)
tg3.c:v2.5 (December 22, 2003)
eth1: Tigon3 [partno(3C996B-T) rev 0105 PHY(5701)] (PCI:33MHz:32-bit)
10/100/1000BaseT Ethernet 00:04:76:f6:8a:a0
ethtool -C eth1 fails with a
"Cannot get device coalesce settings: Operation not supported"
wich comes from the following syscall
ioctl(3, 0x8946, 0xbffffa60) = -1 EOPNOTSUPP (Operation not supported)
I think it's really supported, so why it fails? solutions?
Note, it is a 64bit card plugged in a 32bit slot
I have been using this card quite time and it works ok, except that it seems
to do not work with NAPI, a feature it should support too (I get +15000
interrupts/s)
I think NAPI is always enabled in the driver, isn't it?
another question: I suposse that
ethtool interrupt coalescing settings ! = NAPI
isn't it?
Thanks in advance
Ulisses
