Re: [PATCH bpf-next v3 0/2] Allow data_meta size > 32

Currently, there is no reason for data_meta to be limited to 32 bytes.
Loosen this limitation and make maximum meta size 252.

First I though you made a type here with 252 bytes, but then I 
remembered the 4 byte alignment.
I think commit message should elaborate on why 252 bytes.

Also, modify the selftest, so test_xdp_context_error does not complain
about the unexpected success.

v2->v3:
* Fix main patch author
* Add selftests path

v1->v2:
* replace 'typeof(metalen)' with the actual type
