Replace iovec-based packet assembly with direct linear copy in queue_push_ndlc_flow(). The scatter-gather approach was creating temporary stack variables and looping through iovecs unnecessarily for simple header + msg + tail construction. Scatter-gather makes sense for zero-copy I/O, not for building new packets from scratch. Signed-off-by: Madrajib Lab <madhabsharma94@gmail.com>
