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 ]

Support 5787 hardware TSO using a new flag TG3_FLG2_HW_TSO_2.
Since the TSO interface is slightly different and these chips have
finally fixed the 4GB DMA problem and do not have the 40-bit DMA
problem, a new hard_start_xmit is used for these chips. All previous
chips will use the old hard_start_xmit that is now renamed
tg3_start_xmit_dma_bug().

struct neigh_ops currently has a destructor field, which no in-kernel
drivers outside of infiniband use. The infiniband/ulp/ipoib in-tree
driver stashes some info in the neighbour structure (the results of
the second-stage lookup from ARP results to real link-level path), and
it uses neigh->ops->destructor to get a callback so it can clean up
this extra info when a neighbour is freed. We've run into problems
with this: since the destructor is in an ops field that is shared
between neighbours that may belong to different net devices, there's
no way to set/clear it safely.
The following patch moves this field to neigh_parms where it can be
safely set, together with its twin neigh_setup. Two additional
patches in the patch series update ipoib to use this new interface.

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.
This patch contains ring init code changes only. This next patch
contains rx data path code changes.
