Subject: pull request: Linux-firmware: Add cxgb4 firmware config files

Hi,

Chelsio driver loads firmware configuration file to allow
firmware to distribute resources before chip bring up. Chelsio NIC
driver, cxgb4 searches for firmware config file at /lib/firmware/cxgb4/
directory.

Two predefined configuration files are available - default and
hashfilter. Default configuration file equally distributes
resources across all features, such as iSCSI, iWARP, Crypto, etc.
On the other hand, hashfilter configuration file borrows some
resources by disabling the iSCSI, iWARP, Crypto, etc. features,
and redistributes them to increase offloading more number of flows
to hardware via tc-flower.

Please pull the files to /lib/firmware/cxgb4/config directory
and create a t6-config.txt symbolic link in /lib/firmware/cxgb4/ to
/lib/firmware/cxgb4/config/t6-config-default.txt. The same needs
to be done for t5-config-default.txt and t4-config-default.txt.

The directory structure should look like below.
# tree /lib/firmware/cxgb4/
.
├── config
│   ├── t4-config-default.txt
│   ├── t5-config-default.txt
│   ├── t5-config-hashfilter.txt

├── t5-config.txt -> config/t5-config-default.txt
├── t6-config.txt -> config/t6-config-default.txt
