hello,

with enabled tso4 hardware capabilities my Intel nic reports

...
wm0: device timeout (txfree 3790 txsfree 0 txnext 3078)
wm0: device timeout (txfree 3905 txsfree 0 txnext 1370)
wm0: device timeout (txfree 3907 txsfree 0 txnext 3408)
...

The connected switch shows link-down/link-up messages.

With disabled tso capabilities everything works well. Intel NICs with
other chipsets work well even with enabled tso4.


My hardware:

wm0 at pci9 dev 0 function 0: Intel PRO/1000 PT (82571EB), rev. 6
wm0: interrupting at ioapic0 pin 16
wm0: PCI-Express bus
wm0: 65536 word (16 address bits) SPI EEPROM
wm0: Ethernet address 00:15:17:0e:98:5e
igphy0 at wm0 phy 1: Intel IGP01E1000 Gigabit PHY, rev. 0
igphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseT, 1000baseT-FDX, auto

The nic is connected to a cisco c2960G.


Is it a netbsd bug or maybe a hardware problem?


Thank you for your efforts
Uwe

Sorry, I'm not familiar with the TSO code for wm. Is there anyone who can
debug it?
