The primary aim is to add skb_frag_(ref|unref) in order to remove the use of
bare get/put_page on SKB pages fragments and to isolate users from subsequent
changes to the skb_frag_t data structure.

Now, when vlan tag on untagged in non-accelerated path is stripped from
skb, headers are reset right away. Benefit from that and avoid calling
__netif_receive_skb recursivelly and just use another_round.

We'll either hit one of the case labels or the default in the switch
and in all cases do we then 'goto out' and we also have a 'goto out'
after the switch that is redundant. Change to just use break in the
case statements and leave the 'goto out' after the lop for everyone to
hit.

In commit 9aa32835 (ehea/ibm*: Move the
IBM drivers) the IBM_NEW_EMAC* were renames to IBM_EMAC*

The conversion was incomplete so that even if the driver was added to
the .config it wasn't built, but there were no errors).  In this commit
we also update the various defconfigs that use EMAC to use the new
Kconfig symbol, and explicitly add the NET_VENDOR_IBM guard.

We do not explicitly select the Kconfig dependencies, as this would force
EMAC on.  Doing it in the defconfig allows more flexibility.

It's after all necessary to do reset headers here. The reason is we
cannot depend that it gets reseted in __netif_receive_skb once skb is
reinjected. For incoming vlanids without vlan_dev, vlan_do_receive()
returns false with skb != NULL and __netif_reveive_skb continues, skb is
not reinjected.

This might be good material for 3.0-stable as well
