Re: [net-next 05/10] igb: Update igb to use a path similar to ixgbe to determine when to stop Tx

For igb the IGB_MAX_DATA_PER_TXD is 32K as well.  So if I am not
mistaken we should be fine.  The only time we risk exceeding that is
if we have 64K page size.  It sounds like we may need to work in the
ixgbe driver though since I believe the limit for it is only 16K per
descriptor.

I will also submit an update for this patch that replaces PAGE_SIZE
with NETDEV_FRAG_PAGE_MAX_SIZE in order to keep the two in sync.

I therefore expect a respin of this series from Jeff once the
update of this patch is resolved.

Thanks.
