PE R310/510 Special NIC Bonding

Hello everyone,

we have some R510 with the Dual-NIC Broadcom onboard and an PCIe Intel 
Single-Port GigE Card separately attached.

We now setup a Linux Bonding (Debian Squeeze latest with ifenslave-2.6) 
using settings below and i want to ask if its okay or not to use one 
Broadcom and the Intel Card in a Bond together or if its better to use 
NICs from the same vendor for that (the 3rd NIC is a normal iface)

We saw issues with SLES11 on R310 while bonding them (mode4 LACP) and 
using an IPSec Tunnel over this with the following error. so i want to ask

2012:05:24-09:42:22 seth kernel: [659323.689392] ppp0 received packet on 
queue 2, but number of RX queues is 1

bonding on that 510 is mode 1 active/backup. - here the config (eth0/1 
is internal broadcom, eth2 intel pcie) - i dont think that this causes 
similar errors because only one card is active and not both the same 
time like on the SLES11 we have a mode=4 bonding.
