Comment 9 Hushan Jia 2011-03-24 03:35:23 UTC

Hi, to test this bug, wow to check TSS is disabled within tg3 driver?

Comment 10 Hushan Jia 2011-03-24 03:36:11 UTC

(In reply to comment #9)
meant how to check TSS is disabled within tg3 driver?

Comment 11 Matt Carlson 2011-03-24 18:15:56 UTC

If TSS is enabled, MSIX vector 0 shouldn't fire more than a couple times for link interrupts.  If you start something like netperf, vector 0's interrupt counters in /proc/interrupts should stay stationary.
