Dumitrescu, Cristian March 24, 2021, 11:36 a.m. UTC
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.

For some pipeline instructions (add/sub, srl/shr, jmplt/jmpgt), only
the H, M and I cases were handled, while the E, F and T cases were
disregarded. This is what we fix here.

Fixes: baf7999303d0 ("pipeline: introduce SWX add instruction")
Fixes: c88c62943818 ("pipeline: introduce SWX subtract instruction")
Fixes: b09ba6d0a3c2 ("pipeline: introduce SWX SHL instruction")
Fixes: e0f51638b715 ("pipeline: introduce SWX SHR instruction")
Fixes: b3947e25bed4 ("pipeline: introduce SWX jump and return instructions")
