Comment 21 for bug 1504801

The BIOS was updated:

P89
05/06/2015

We are still seeing drops on the bonded interfaces and the slave nic. The host has not been rebooted since the BIOS upgrade so all drop counts are new and current.

For example:

auto em4
iface em4 inet manual
 bond-master bond3
 bond-primary em4

auto em2
iface em2 inet manual
        bond-master bond3

bond3 - RX dropped:2581
em2 - RX dropped:1290
em4 - RX dropped:0

During a previous test (post reboot) I broke the bonding as still saw drops on em4 with minimal data. See my comment from 2015-10-21

Happy to provide further details upon request.
