Changing NIC ring weight in indirection table

[David Belle-Isle]

Hi,

Can anyone tell me how to set the weight of a ring from the indirection
table on FreeBSD? My plan is to yank out a TX ring and to use it solely
with netmap to receive packets but want to make sure the kernel won't be
receiving any packets on this ring.

Based on a quick search this is something that ethtool would be able to do
on Linux but I doubt this can be done on FreeBSD using the same tool?

Thanks for your help,

David
