Summary:                    [patch] Add TDMoE Multi-Frame support
Description: 
A patch against SVN rev 4904, to add TDMoE Multi-Frame support as described
in the article at the following URL:

http://www.thrallingpenguin.com/articles/tdmoe-mf.htm

TDMoE-MF is known to be implemented in hardware solutions from Redfone
Communications.

This patch additionally implements RCU within dahdi_dynamic to decrease
lock contention, latency, and context switching. Because of the use of RCU
locking, all prior known issues with loading and unloading of the modules
are resolved, providing the spans are shutdown with "dahdi_cfg -s".

It also contains an attempt, which works, at fixing a kernel change with
skb_linearize(). The use of kernel version number does not work with SuSE
SLES 10, as it appears they have backported the 2.6.18 change in to their
2.6.16 version.
