In code manipulating the TM State Low register of 802.11 cores, two
different magic numbers are used to reference the 'G Mode Enable' bit.
One of these, 0x20000000, is clear, but the other, (0x800 << 18), is not.
This patch replaces both types with a defined constant. In addition, two
bits in the TM State High registers are given definitions to help in
following the code.

So that it is also an offset from skb->head, reduces its size from 8 to 4 bytes
on 64bit architectures, allowing us to combine the 4 bytes hole left by the
layer headers conversion, reducing struct sk_buff size to 256 bytes, i.e. 4
64byte cachelines, and since the sk_buff slab cache is SLAB_HWCACHE_ALIGN...
:-)

Many calculations that previously required that skb->{transport,network,
mac}_header be first converted to a pointer now can be done directly, being
meaningful as offsets or pointers.

For the common, open coded 'skb->nh.raw = skb->data' operation, so that we can
later turn skb->nh.raw into a offset, reducing the size of struct sk_buff in
64bit land while possibly keeping it as a pointer on 32bit.

This one touches just the most simple case, next will handle the slightly more
"complex" cases.

For the places where we need a pointer to the mac header, it is still legal to
touch skb->mac.raw directly if just adding to, subtracting from or setting it
to another layer header.

This one also converts some more cases to skb_reset_mac_header() that my
regex missed as it had no spaces before nor after '=', ugh.

Due to conflicting/confusing defines in the vendor driver, we were
reading E2P_PHY_REG from the wrong location.

CR157 patching was slightly incorrect in that the vendor driver only
patches in an 8-bit value, whereas we were patching 24 bits.

Additionally, CR157 patching was happening on both zd1211 and zd1211b,
but this should only happen on zd1211.

During testing of bcm43xx interference mitigation, two problems were
discovered:

(1) When the MANUALWLAN mode was set, routines _stack_save and _stack_restore
    generated assertions that were traced to saving ILT registers with addresses
    > 0xFFF. This problem was fixed by adding one bit to the field used for
    the offset, and subtracting one bit from the space used for the id.
(2) In MANUALWLAN mode, the IRQ XMIT errors are generated. The cause of these
    errors has not yet been located. Any suggestions on debugging this problem
    would be greatly appreciated.
