hme driver can deadlock when receive/send and snoop of hme are done at the same time.
I built a test hme driver, and am testing it in Newark LAB. Due to heavy network
traffic generated by test, the testing was killed several time by network monitor.
I'll merge the fix code if test passed.
I am testing the fix. Due to Newark LAB network dow and machine PCI bus iommu error,
the test was interrupted every 2 or 3 days. I'll emerge the fixing code if test
could run as long as a week. I just restarted test this morning, it wasinterrupted
by PCI bus iommu error.
The binary fix had solved the problem of deadlock on customer (1-2216121) system
