wl1251: Cherry-pick of support for PG11 chips

To do (or not):

acard-ahci: New driver.  Depends on ahci/libahci split so would be tricky
            to backport.
ath9k: add support for newer AR9285 chipsets
ath9k: add support for AR9271 chipset (fb9987d0f748c983bb795a86f47522313f701a08)
       and AR9300 (db3cc53a2faea2da5730304af06a77d343f314a5)
ath9k: add support for the AR9003 2.2 (7284635d2dbc0e055d14bc488c69f8c1d2822ae7)
       and AR7010 (b176286276f85e10e8ab3342730c5e39e1ce460b)
ath9k: add support for AR9485 (1435894dcd263fdbdd5e1ea2a684289dff187c34)
atl1c: Add support for AR8151 v2 (8f574b35f22fbb9b5e5f1d11ad6b55b6f35f4533).
       There are many other changes in the same commit.
be2iscsi: Add support for BE3 (f98c96b0b6572b5491e954148509b20f08f31491).
          This was a new driver in 2.6.32 and based on subsequent commits
          appears to be quite broken.  I would suggest a wholesale backport.
be2net: add support for Lancer (fe6d2a38b2076cba515dc95b5dc1589a7ab51c17)
bnx2x: Add 57712 support (f2e0899f0f275cc3f5e9c9726178d7d0ac19b2db).
       This makes many changes to existing code and will need testing on
       old and new devices.
carl9170: New driver, but seems to be meant as a replacment for ar9170usb
          and has the same device IDs.
cnic: Add support for 57712 device (ee87a82a28cddbb9267a294172ecb3d3d3bdaa6c).
      Probably depends on bnx2x.

cxgb4i: new driver
e1000: add support for CE4100 (5377a4160bb65ee4dd11b4b1d081d86d56d92bff);
       probably not important

        (fb30eaf38703d7562606e49a5872745d66366a50), update PCI ID for 6000g2b
        series devices (8b37d9f0a1e114a1c7f5082842fb310a81ea3732)

rt2x00: add support for RT2800P/RT2800E family; probably redundant with
rt2x00: Add initial support for RT3370/RT3390 devices
        (f93bc9b3ce379800b30b3c2f4fc945ae35a80039); not sure what to do
        with this

smsc75xx: new driver
tg3: Add support for 5717 and 57765. Dependencies are complex.           
uas: new driver


Of the existing drivers, I would guess that ath9k, e1000e, igb, iwlagn,
iwlwifi, r8169, rt2x00 and tg3 are the most widely used.  Unfortunately
they are also updating quite frequently and likely to be hard to
cherry-pick changes from.  So I think we should do some combination of:

1. Look at what other distributions with Linux 2.6.32 have done with
2. Ask for guidance from the upstream maintainers
3. Where the driver is vendor-maintained, request that the vendor
   tests the backport
4. Try to get broad testing by users in s-p-u or a separate repository

We have fairly limited time to do this before 6.0.2 so whatever we do we
need to move fast.
