netmap_if request size 1208 too large with ixgbe

[GoogleCodeExporter]

Hello!

I tried to use netmap for my tool https://github.com/FastVPSEestiOu/fastnetmon 
but I can't run netmap on my server.

Debian 7 with 3.2.0-4-amd64

I tried with upstream ixgbe driver, patch it (partly manually) and run.

And after this I run it:
modprobe ixgbe RSS=1
insmod /usr/src/netmap/LINUX/netmap_lin.ko

But when I run test tool:
./pkt-gen -i eth3

And got error:
[386328.259539] 159.325204 [1049] netmap_mem_global_config  reconfiguring
[386328.294497] 159.360262 [ 385] netmap_obj_malloc         netmap_if request 
size 1208 too large
[386328.295880] 159.361649 [ 753] generic_netmap_dtor       Restored native NA  
         (null)

This error was fixed by ifconfig eth3 up but can't you add sanity checks and 
more understandable error message for this case?
