If anyone has any objections, please let me know. ------------------ From: Namjae Jeon [ Upstream commit cb097b3dd5ece9596a0a0b7e33893c02a9bde8c6 ] When SMB Direct is used with iWARP, Windows use 5445 port for smb direct port, 445 port for SMB. This patch check ib_device using ib_client to know if NICs type is iWARP or Infiniband.
