Subject: Re: [PATCH V2] cdc_ncm: Add support for moving NDP to end of NCM
 frame

When sending lots of small packets, this patch will generate an "Unable to 
handle kernel paging request" in the memset call:
ndp16 = memset(ctx->delayed_ndp16, 0, ctx->max_ndp_size);
And I don't know why.
Any comment or suggestion would be greatly apreciated.
This has been reproduced in a QEMU X86 VM, from kernel 4.0.4 to current git.
Thanks,
Enrico Mioso
