This patch contains the following linux kernel feature:

Summary:
lcs: Replace the original lcs driver with the backport of the lcs driver for Linux kernel 2.6.
Note: The lcs-driver in this patch is functionally equivalent to the kernel 2.6.5 lcs-driver from the "April 2004 stream", up to patch 10, dated 2004-11-30 (Problem-ID: 12485).
Description:
The original driver has some timing problems which are all related to bugs in the interrupt handler. Any changes in this code would lead to a complete design change and thus almost a rewrite.
The new lcs driver has passed a complete regression test so that we rather replace the old one than adding the new one as an alternative.
Note: chandev parameter use_hw_stats and checksum_received_ip_pkt<-s are not supported anymore with the new lcs driver.

Everybody should apply this patch.
