Hi,
Thanks, is there a way to increase the tx/rx descriptor, i see this for 1G
and 10G interface, both have a 4096 max:
rx: queues 1 (max 192), desc 1024 (min 64 max 4096 align 32)
tx: queues 38 (max 192), desc 1024 (min 64 max 4096 align 32)
rx: queues 1 (max 8), desc 1024 (min 32 max 4096 align 8)
tx: queues 8 (max 8), desc 1024 (min 32 max 4096 align 8)
But in maillist, i saw some mail that thay have a 10G interface with 65500
descriptor, why?
