cxgbit, iw_cxgb4, cxgb4i and chcr. The resources allocated include Tx
queues which are allocated when ULD register with cxgb4 driver and freed
while un-registering. The Tx queues which are shared by ULD shall be
allocated by first registering driver and un-allocated by last

The Chelsio's Crypto Hardware can perform the following operations:
SHA1, SHA224, SHA256, SHA384 and SHA512, HMAC(SHA1), HMAC(SHA224),
HMAC(SHA256), HMAC(SHA384), HAMC(SHA512), AES-128-CBC, AES-192-CBC,
AES-256-CBC, AES-128-XTS, AES-256-XTS
This patch implements the driver for above mentioned features. This
driver is an Upper Layer Driver which is attached to Chelsio's LLD
(cxgb4) and uses the queue allocated by the LLD for sending the crypto
requests to the Hardware and receiving the responses from it.
The crypto operations can be performed by Chelsio's hardware from the
userspace applications and/or from within the kernel space using the
kernel's crypto API.
The above mentioned crypto features have been tested using kernel's
tests mentioned in testmgr.h. They also have been tested from user
space using libkcapi and Openssl.
