wil6210: add debugfs 'mids' file
Added a new debugfs file 'mids' to print the list of virtual interfaces by MAC ID (MID). Allows mapping between the internal MID used by FW and the actual network interface used by the VIF. This is needed by debugging tools. Signed-off-by: Lior David <liord@codeaurora.org> Signed-off-by: Maya Erez <merez@codeaurora.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
