Comment 9 Hushan Jia 2011-03-23 23:35:23 EDT

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

Comment 10 Hushan Jia 2011-03-23 23:36:11 EDT

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

Comment 11 Matt Carlson 2011-03-24 14:15:56 EDT

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.

Comment 12 Chris Ward 2011-04-06 07:04:23 EDT
