This change will have sequential validation support
& patch config command is added

Signed-off-by: Sai Teja Aluvala <quic_saluvala@quicinc.com>

v4:
* addressed the change from u8 cmd to const u8 cmd

v3:
* removed rlen,rtype
* Replaced kfree with kfree_skb

v2:
* Added static declaration
* Addressed wrong indentation
* Removed EDL_PATCH_CONFIG_CMD_LEN

v1:
*Initial patch

I said this many times before. = {[SPACE], a, b, c[SPACE]};

And I prefer the const pieces first, and int err last.

It is rather pointless to print two error. So just scrap this one.

I said this many times before. = {[SPACE], a, b, c[SPACE]};
[Sai]: i will include spaces & update in next patch

And I prefer the const pieces first, and int err last.
