Eilon Greenstein 4d295db0ef bnx2x: Supporting BCM8727 PHY
Adding support for BCM8727 - a dual port SFP+ PHY. That includes verification of
the optic module vendor and part number - the list of approved modules resides
on the nvram and the module is verified by the FW. Since not all users would
like to use this verification feature, it can be disabled. The default behavior
is to issue a warning if the module is not approved, but still allow using it -
but it is also possible to disable the link if the module is not approved.

Andy Grover 02a6a2592e RDS/IB: Handle connections using RDS 3.0 wire protocol
The big differences between RDS 3.0 and 3.1 are protocol-level
flow control, and with 3.1 the header is in front of the data. The header
always ends up in the header buffer, and the data goes in the data page.

In 3.0 our "header" is a trailer, and will end up either in the data
page, the header buffer, or split across the two. Since 3.1 is backwards-
compatible with 3.0, we need to continue to support these cases. This
patch does that -- if using RDS 3.0 wire protocol, it will copy the header
from wherever it ended up into the header buffer.

Jarek Poplawski be916cdebe ipv4: Fix inflate_threshold_root automatically
During large updates there could be triggered warnings like: "Fix
inflate_threshold_root. Now=25 size=11 bits" if inflate() of the root
node isn't finished in 10 loops. It should be much rarer now, after
changing the threshold from 15 to 25, and a temporary problem, so
this patch tries to handle it automatically using a fix variable to
increase by one inflate threshold for next root resizes (up to the 35
limit, max fix = 10). The fix variable is decreased when root's
inflate() finishes below 7 loops (even if some other, smaller table/
trie is updated -- for simplicity the fix variable is global for now).

Jarek Poplawski c3059477fc ipv4: Use synchronize_rcu() during trie_rebalance()
During trie_rebalance() we free memory after resizing with call_rcu(),
but large updates, especially with PREEMPT_NONE configs, can cause
memory stresses, so this patch calls synchronize_rcu() in
tnode_free_flush() after each sync_pages to guarantee such freeing
(especially before resizing the root node).

The value of sync_pages = 128 is based on Pawel Staszewski's tests as
the lowest which doesn't hinder updating times. (For testing purposes
there was a sysfs module parameter to change it on demand, but it's
removed until we're sure it could be really useful.)

The patch is based on suggestions by: Paul E. McKenney

Mike Frysinger 37cf2b8d16 connector: get test code working by default
The connector test code currently does not work out of the box.  This is
because it uses a connector id that is above the registered limit.  So
rather than force people to stumble through undocumented code wondering
why it isn't working, have the test code use one of the "private" ids by
default.  While I'm in here, clean up the code (kernel and user app) so
that it's a bit more user friendly and verbose in significant things that
it does.  Terse test code wastes people time as they simply enumerate it
with all the same kind of debug messages to get a better feel of what code
is running at any time.

Mike Frysinger 0741241c6b connector: make callback argument type explicit
The connector documentation states that the argument to the callback
function is always a pointer to a struct cn_msg, but rather than encode it
in the API itself, it uses a void pointer everywhere.  This doesn't make
much sense to encode the pointer in documentation as it prevents proper C
type checking from occurring and can easily allow people to use the wrong
pointer type.  So convert the argument type to an explicit struct cn_msg
pointer.
