Module Name: src
Committed By: jym
Date: Thu Sep 22 08:42:53 UTC 2011
Modified Files:
src/sys/dev/pci: if_bnx.c
Log Message:
The bnx(4) handler runs at IPL_NET (works with spin mutexes), while
allocations can be deferred to a workqueue(9): set its highest IPL to
IPL_NET and not IPL_NONE, which is protected by an adaptive/sleeping mutex.
