[Xen-devel] [PATCH 2/4] net: Detect drivers that reschedule NAPI and exhaust budget

2014-12-20 Thread Herbert Xu

The commit d75b1ade567ffab085e8adbbdacf0092d10cd09c (net: less interrupt masking in NAPI) required drivers to leave poll_list empty if the entire budget is consumed. We have already had two broken drivers so let's add a check for this. Signed-off-by: Herbert Xu --- net/core/dev.c |9 ++
