[spp] [PATCH 3/3] spp_pcap: revise enum spp_port_rxtx

[yasufum.o@gmail.com]

From: Yasufumi Ogawa <yasufum.o@gmail.com>

This update is to revise the name of enum `spp_port_rxtx` to
`sppwk_port_dir` because it is used to specify which of direction
packets are forwarded on a port. Term `rxtx` is used for a set of RX and
TX, so it should not be used for specifying the direction. This update
is also rename members of the enum, and a member of structs using this
enum from `rxtx` to `dir`.
