Subject: net: treewide use of RCU_INIT_POINTER

rcu_assign_pointer(ptr, NULL) can be safely replaced by
RCU_INIT_POINTER(ptr, NULL)

(old rcu_assign_pointer() macro was testing the NULL value and could
omit the smp_wmb(), but this had to be removed because of compiler
warnings)

Subject: bnx2x, cnic: support DRV_INFO upon FW request

Add support to send driver capabilities, settings and statistics to
management firmware.

[ Redone using many local variables, removed many unnecessary inlines,
  and put #defines at the left margin suggested by Joe Perches ]

Subject: cnic: Improve error recovery on bnx2x devices

When a bnx2x device encounters parity errors, it will not respond to all
SPQ messages.  As a result, the shutdown sequence before reset can take
a long time as the ulp drivers (bnx2i/bnx2fc) have to wait for timeout
of all such messages.

To improve this scenario, when bnx2x returns error on the SPQ, we'll send
an immediate response to the ulp drivers to avoid such lengthy timeouts.

Adjust the return code of relevant functions to return error only if
the message cannot be sent on the SPQ so that we'll generate an error
completion to the ulp drivers.

ip6_route_output() never returns NULL, so it is wrong to
