Increasing MAX_SKB_FRAGS was a patch in BIG TCP v1 submission.

It appears this might take time to validate that all drivers
are ready for this change.

I have removed from BIG TCP series this patch, and made
a separate series.

MAX_SKB_FRAGS is now configurable (from 17 to 45),
and the default is 17.

Eric Dumazet (4):
  af_packet: do not assume MAX_SKB_FRAGS is unsigned long
  scsi: iscsi: do not assume MAX_SKB_FRAGS is unsigned long
  net: mvpp2: get rid of hard coded assumptions
  net: introduce a config option to tweak MAX_SKB_FRAGS
