The mt7921 and mt7925 firmware event parsers validate some outer skb
lengths, but several paths still trust type-specific lengths before
reading fixed fields. Malformed responses can make the drivers read past
a TLV payload, and a zero-length mt7925 capability TLV can stop progress
through the response.
Validate the fixed and type-specific payload extents before consuming
NIC capability and debug message data. Each patch covers one independent
parser and can be applied separately.
