Doc Type: Bug Fix
Doc Text:
Cause: the Emulex "be2net" 10g NIC driver present on mrg-2.0 was not part of the effort to synchronize the network drivers from mrg-2.0 with the ones present in RHEL6. For short, the be2net driver in mrg-2.0 is an old version. Consequence: a customer observed the newer driver (present in rhel6 and rhel5.6) had better performance. Fix: upgrade the be2net driver in mrg-2.0 Result: mrg-2.0 has the same driver present in rhel6, with the same features.

Verified.

Checked that the MRG2.0 be2net is the same version as shipped in RHEL6.1:

[root@mrg39 ~]# modinfo /lib/modules/2.6.32-131.0.15.el6.x86_64/kernel/drivers/net/benet/be2net.ko /lib/modules/2.6.33.9-rt31.73.el6rt.x86_64/kernel/drivers/net/benet/be2net.ko | egrep "filename:|version:"
filename:       /lib/modules/2.6.32-131.0.15.el6.x86_64/kernel/drivers/net/benet/be2net.ko
version:        2.103.298r
srcversion:     1B885838977704EF64FD2E4
filename:       /lib/modules/2.6.33.9-rt31.73.el6rt.x86_64/kernel/drivers/net/benet/be2net.ko
version:        2.103.298r
srcversion:     1B885838977704EF64FD2E4

Ran several network tests and found now issues.
