What?
Rename
max_put_sgl_zcopy_counttomax_sgl_zcopy_countin the multi-lane protocol private data, and query the matching UCT attribute for put or get.Why?
Preparation for the SGL get offload protocols, which need the same per-lane limit.
How?
A protocol is either put or get, so the direction is decided once from its
tl_v2_cap_flags. No functional change.
