Herbert Xu 5b057c6b1a [NET]: Avoid allocating skb in skb_pad 
First of all it is unnecessary to allocate a new skb in skb_pad since
the existing one is not shared.  More importantly, our hard_start_xmit
interface does not allow a new skb to be allocated since that breaks
requeueing.

This patch uses pskb_expand_head to expand the existing skb and linearize
it if needed.  Actually, someone should sift through every instance of
skb_pad on a non-linear skb as they do not fit the reasons why this was
originally created.

Incidentally, this fixes a minor bug when the skb is cloned (tcpdump,
TCP, etc.).  As it is skb_pad will simply write over a cloned skb.  Because
of the position of the write it is unlikely to cause problems but still
it's best if we don't do it.

	------

	This directory is mostly for Wireless LAN drivers, in their
various incarnations (ISA, PCI, Pcmcia...).
	This separate directory is needed because a lot of driver work
on different bus (typically PCI + Pcmcia) and share 95% of the
code. This allow the code and the config options to be in one single
place instead of scattered all over the driver tree, which is never
100% satisfactory.

	Note : if you want more info on the topic of Wireless LANs,
you are kindly invited to have a look at the Wireless Howto :
		http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/
	Some Wireless LAN drivers, like orinoco_cs, require the use of
Wireless Tools to be configured :
		http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html

	Special notes for distribution maintainers :
	1) wvlan_cs will be discontinued soon in favor of orinoco_cs
	2) Please add Wireless Tools support in your scripts

	Have fun...
