This fixes a regression added by ec3c0982
("[TCP]: TCP_DEFER_ACCEPT updates - process as established")

tcp_v6_do_rcv()->tcp_rcv_established(), the latter goes to step5, where
eventually skb can be freed via tcp_data_queue() (drop: label), then if
check for tcp_defer_accept_check() returns true and thus
tcp_rcv_established() returns -1, which forces tcp_v6_do_rcv() to jump
to reset: label, which in turn will pass through discard: label and free
the same skb again.

Tested by Eric Sesterhenn.

Previously digest_null had no setkey function which meant that
we used hmac(digest_null) for IPsec since IPsec always calls
setkey.  Now that digest_null has a setkey we no longer need to
do that.

In fact when only confidentiality is specified for ESP we already
use digest_null directly.  However, when the null algorithm is
explicitly specified by the user we still opt for hmac(digest_null).

This patch removes this discrepancy.  I have not added a new compat
name for it because by chance it wasn't actualy possible for the user
to specify the name hmac(digest_null) due to a key length check in
xfrm_user (which I found out when testing that compat name :)

In commit ba749ae9 ([XFRM]: alg_key_len
should be unsigned to avoid integer divides
<http://git2.kernel.org/?p=linux/kernel/git/davem/net-2.6.git;a=commitdiff;h=ba749ae98d5aa9d2ce9a7facde0deed454f92230>)
alg_key_len field of struct xfrm_algo was converted to unsigned int to
avoid integer divides.

Then Herbert in commit 1a6509d9
([IPSEC]: Add support for combined mode algorithms) added a new
structure xfrm_algo_aead, that resurrected a signed int for alg_key_len
and re-introduce integer divides.

This patch avoids these divides and saves 64 bytes of text on i386.

- vlans were using a single CAM register (see mac_set_vlan_cam)
- setting the address filtering registers for vlans is not
  needed when there is no vlan

The non-tagged interface is filtered out as soon as a tagged
(!= 0) interface is created. Its traffic appears again when an
zero-tagged interface is created.

Tested on Via Epia SN (VT6130 chipset) with several vlans whose
tag was above or beyond 255.

default will be set to disabled.

gianfar was unable to handle failed skb allocation for rx buffers, so
we were spinning until it succeeded.  Actually, it was worse--we were
spinning for a long time, and then silently failing.  Instead, we take
Stephen Hemminger's suggestion to try the allocation earlier, and drop the
packet if it failed.

We also make a couple of tweaks to how buffer descriptors are set up.

Since 43cc71ee, the platform modalias is
prefixed with "platform:".  Add MODULE_ALIAS() to the hotpluggable network
platform drivers, to re-enable auto loading.

NOTE: didn't change drivers/net/fs_enet/fs_enet-main.c "old binding" support.
That looks problematic in the first place (it even uses the ancient "struct
device_driver" binding scheme for platform_bus!) and I suspect it will vanish
soonish when arch/powerpc rules the world.  Also, drivers/net/ne.c would have
needed more thought to sort out.

Sometimes the specific interaction between the platform and the PHY
requires special handling.  For instance, to change where the PHY's

Lib to be called on matching PHYs when they are brought up, or reset.
