[dpdk-stable] [dpdk-dev] [PATCH] pipeline: fix endianness conversions

> The SWX pipeline instructions work with operands of different types:
> header fields (h.header.field), packet meta-data (m.field), extern
> object mailbox field (e.obj.field), extern function (f.field), action
> data read from table entries (t.field), or immediate values; hence the
> HMEFTI acronym. The H operands are stored in network byte order (NBO),
> while the MEFT operands are stored in host byte order (HBO), hence the
> need to operate endianness conversions.
> 
> Some of the endianness conversion macros were not working correctly
> for some cases such as operands of different sizes, and they are fixed
> now. Affected instructions: mov, and, or, xor, jmpeq, jmpneq.
