To solve a networking bug where Broadcom 10 Gigabit Ethernet NICs would throw crash information on HP ProLiant DL980 G7 servers when used for a virtual machine network, resulting in adverse performance, TPA is disabled for the bnx2x driver module.

If the port is used for dom0 traffic only, you can enable TPA by creating an entry for the bnx2x module in /etc/modprobe.d/ovm.conf on the Oracle VM Servers that are affected:

options bnx2x disable_tpa=0
