tty: n_gsm: Modify CR,PF bit when config requester
When n_gsm config "initiator=0",as requester,gsmld receives dlci SABM/DISC control command frame,but send UA frame is error. Example: Gsmld receive dlc0 SABM frame "f9 03 3f 01 1c f9",now it sends UA frame "f9 01 63 01 a3 f9",CR and PF bit are 0,but it should be set 1 from requster to initiator. Kernel test log as follows: Before modify [ 271.732031] c1 gsmld_receive: 00000000: f9 03 3f 01 1c f9 [ 271.741719] c1 <-- 0) C: SABM(P) [ 271.749483] c1 gsmld_output: 00000000: f9 01 63 01 a3 f9 [ 271.758337] c1 --> 0) R: UA(F) After modify [ 261.233188] c0 gsmld_receive: 00000000: f9 03 3f 01 1c f9 [ 261.242767] c0 <-- 0) C: SABM(P) [ 261.250497] c0 gsmld_output: 00000000: f9 03 73 01 d7 f9 [ 261.259759] c0 --> 0) C: UA(P) Signed-off-by: Zhenguo Zhao <Zhenguo.Zhao1@unisoc.com> Link: https://lore.kernel.org/r/1629461872-26965-3-git-send-email-zhenguo6858@gmail.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
