Stephen Hemminger 8f182b494f [LLC]: allow applications to get copy of kernel datagrams
It is legal for an application to bind to a SAP that is also being
used by the kernel. This happens if the bridge module binds to the
STP SAP, and the user wants to have a daemon for STP as well.
It is possible to have kernel doing STP on one bridge, but
let application do RSTP on another bridge.

Stephen Hemminger 23dbe7912d [LLC]: use rcu_dereference on receive handler
The receive hander pointer might be modified during network changes
of protocol. So use rcu_dereference (only matters on alpha).

David S. Miller 5185db09f4 [LLC]: Use pskb_trim_rcsum() in llc_fixup_skb().
Kernel Bugzilla #6409

If we use plain skb_trim(), that's wrong, because if
the SKB is cloned, and it can be because we unshared
it in the caller, we have to allow reallocation.  The
pskb_trim*() family of routines is therefore the most
appropriate here.

Jochen Friedrich 096f0eb1df [LLC]: Fix llc_fixup_skb() bug
llc_fixup_skb() had a bug dropping 3 bytes packets (like UA frames). Token ring
doesn't pad these frames.

David S. Miller f2ccd8fa06 [NET]: Kill skb->real_dev
Bonding just wants the device before the skb_bond()
decapsulation occurs, so simply pass that original
device into packet_type->func() as an argument.

It remains to be seen whether we can use this same
exact thing to get rid of skb->input_dev as well.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
