One step closer to dropping all the drm_bus_* code:
Add a driver->set_busid() callback and make all drivers use the generic
helpers. Nouveau is the only driver that uses two different bus-types with
the same drm_driver. This is totally broken if both buses are available on
the same machine (unlikely, but lets be safe). Therefore, we create two
different drivers for each platform during module_init() and set the
set_busid() callback respectively.

net: enable GRO for IPIP and SIT
This patch sets populates the IPIP and SIT offload structures with
gro_receive and gro_complete functions. This enables use of GRO
for these. Also, fixed a problem in IPv6 where we were not properly
initializing flush_id.
Peformance results are below. Note that these tests were done on bnx2x
which doesn't provide RX checksum offload of IPIP or SIT (i.e. does
not give CHEKCSUM_COMPLETE). Also, we don't get 4-tuple hash for RSS
only 2-tuple in this case so all the packets between two hosts are
winding up on the same queue. Net result is the interrupting CPU is
the bottleneck in GRO (checksumming every packet there).
Testing:
netperf TCP_STREAM between two hosts using bnx2x.

In TCP gro we check flush_id which is derived from the IP identifier.
In IPv4 gro path the flush_id is set with the expectation that every
matched packet increments IP identifier. In IPv6, the flush_id is
never set and thus is uinitialized. What's worse is that in IPv6
over IPv4 encapsulation, the IP identifier is taken from the outer
header which is currently not incremented on every packet for Linux
stack, so GRO in this case never matches packets (identifier is
not increasing).
This patch clears flush_id for every time for a matched packet in
IPv6 gro_receive. We need to do this each time to overwrite the
setting that would be done in IPv4 gro_receive per the outer
header in IPv6 over Ipv4 encapsulation.
