When I increase the ixgbevf rx ring size from 1024 to 4096 I get this:

[ 5526.651780] 851.135009 [ 931] netmap_obj_malloc         netmap_ring request size 65792 too large
[ 5526.652779] 851.136008 [1802] netmap_mem2_rings_create  Cannot allocate RX_ring

What netmap module parameters do I need to tweak to get past this?

I am using LINUX should it matter.
