override speed setting if firmware script issues serial settings command, otherwise the value given in the firmware script will be overridden. Example: hciattach /dev/ttyO1 texas 115200 will fail, because /dev/ttyO1 will be opened with 115200 b/s, then the firmware script will set the buadrate to 3000000 b/s, after UART init hciattach.c will set the baudrate to 115200, so communication is broken. The only correct way is to set both speeds: hciattach -s 115200 /dev/ttyO1 texas 3000000 With this patch only initial speed must be specified. The former semantic will be preserved in case the firmware script doesn't provide serial settings action. Tested with wl1271 and firmware TIInit_7.2.31.bts
