We're now starting to have quite a number of places that do skb_pull
followed immediately by an skb_postpull_rcsum.  We can merge these two
operations into one function with skb_pull_rcsum.  This makes sense
since most pull operations on receive skb's need to update the
checksum.

I've decided to make this out-of-line since it is fairly big and the
fast path where hardware checksums are enabled need to call
csum_partial anyway.

Since this is a brand new function we get to add an extra check on the
len argument.  As it is most callers of skb_pull ignore its return
value which essentially means that there is no check on the len
argument.

Move the netif_carrier_off() call from tg3_init_one()->
tg3_init_link_config() to tg3_open() as is the convention for most other
network drivers.

I was getting a panic after a tg3 device failed to initialize due to DMA
failure.  The oops pointed to the link watch queue with spinlock debugging
enabled.  Without spinlock debugging, the Oops didn't occur.

I suspect that the link event was getting queued but not executed until
after the DMA test had failed and the device was freed.  The link event was
then operating on freed memory, which could contain anything.  With this
patch applied, the Oops no longer occurs.

[ Based upon feedback from Michael Chan, we move netif_carrier_off()
  to the end of tg3_init_one() instead of moving it to tg3_open() -DaveM ]

Increase maximum receive ring size from 255 to 1020 by supporting
up to 4 linked pages of receive descriptors. To accomodate the
higher memory usage, each physical descriptor page is allocated
separately and the software ring that keeps track of the SKBs and the
DMA addresses is allocated using vmalloc.

Some of the receive-related fields in the bp structure are re-
organized a bit for better locality of reference.

The max. was reduced to 1020 from 4080 after discussion with David
Miller.
