Series wifi: rtl8xxxu: Add concurrent mode for 8188f | expand

Commit Message

Martin Kaistra Dec. 22, 2023, 10:14 a.m. UTC 
To prepare for concurrent mode, enhance the set_linktype function to be
able to set the linktype in the MSR register for both hardware ports.

Until the users of set_linktype can handle multiple interfaces, use
port_num = 0.
