| 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. Other NIC drivers tested are: bna, bnx2, bnx2x, chelsio, e100, e1000, e1000e, enic, igb, ixgbe, myri10g, netxen_nic and tg3. An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA.
