v7:
 - Rebased to 21.11 rc3
 - Fix Tx adapter capabilities for SW driver
v6:
 - Rebased to 21.11 rc2
 - Added feature matrices for all supported drivers
 - Added doc vs code check script
 
v5:
 - Rebased to 21.11
 - Added feature matrix for cnxk.
v4:
 - Rebased to 20.02
v3:
 - Removed .txt files to generate tables.
 - Use conf.py script to generate tables.
 - Add .ini file for all supported PMDs.
v2:
 - Review comments incorporated

Following errors[2] need to be taken care in
devtools/parse-event-support.sh by detecting it is using a common Rx
adapter or not?
I have spent some time fixing it, Please find below a test patch for same[1].
Please send the next version with fix. I am planning to merge all doc
patches(1-10) to next-event-dev tree and delegate this
patch(11/11) to Thomas as he is the maintainer for tooling.

[2]
doc out of sync for dsw
        Eth Rx adapter Features event_vector
        Eth Rx adapter Features multi_eventq
        Eth Rx adapter Features override_flow_id
doc out of sync for sw
        Eth Rx adapter Features event_vector
        Eth Rx adapter Features multi_eventq
        Eth Rx adapter Features override_flow_id
