638e970747 IB/usnic: Remove unused prototype
query_protocol() was added in commit 6b90a6d66b ("IB/Verbs:
Implement new callback query_protocol()") and then removed in
commit f9b22e355d ("IB/core: Convert core to use bitfield
for caps").

This left behind an unused prototype.

3805eade3b usnic: add missing clauses to BSD license
The usnic_verbs kernel module was clearly marked with the following in
its code:

  MODULE_LICENSE("Dual BSD/GPL");

However, we accidentally left a few clauses of the BSD text out of the
license header in all the source files.  This commit fixes that: all
the files are properly dual BSD/GPL-licensed.  Contributors that might
have been confused by this have been contacted to get their permission
and are Cc:ed here.

2528e33e68 IB/core: Pass hardware specific data in query_device

we need to pass the vendors' specific udata.

bcf4c1ea58 IB/core: Change provider's API of create_cq to be extendible
Add a new ib_cq_init_attr structure which contains the
previous cqe (minimum number of CQ entries) and comp_vector
(completion vector) in addition to a new flags field.
All vendors' create_cq callbacks are changed in order
to work with the new API.

This commit does not change any functionality.
