This patch allows the ISA-L compression PMD,
to be used with offsets in the mbuf.
Offsets can now be used for source and destination buffers,
during compression or decompression.
Fixes: dc49e6a "compress/isal: add ISA-L compression functionality"
Fixes: 7bf4f06 "compress/isal: add ISA-L decomp functionality"

No need to use ISA-L PMD in the title, as it is a duplicate.
Also, titles always start with verb in infinitive (fix).
So, maybe a suggestion could be: "compress/isal: fix offset usage"?

I would rephrase this to "Input buffer not big enough for the length and offset provided".
Same for inflate.

Actually, I think "avail_out = data_len - dst.offset"

This patch allows the ISA-L compression PMD,
to be used with offsets in the mbuf.
Offsets can now be used for source and destination buffers,
during compression or decompression.
V2 - commit message change.
- error log message reword.
- avail_out not taking offset into account.
