Suitable value for bonding module's tx_queues?

Hi

Please cc me on reply since I'm not subscribed.

I'm wondering when you want to change tx_queues from default 16. Should 
this match the total number of queues of all the members of the bond? 
Let's say I got 2 interfaces, each with 24 queues on a 24 CPU system in 
a bond. Should I load bonding with 24 to match the number of CPUs or 48 
to match the total number of queues of the members, or leave at default 
because it's not relevant?

Thanks!

Unless you add a mq qdisc on the bonding device, "number of tx queues" does not matter
because bonding is a virtual device, with NETIF_F_LLTX
