+Subject: [PATCH 3/3] net: ieee8021541: bcfserial: Increase the number of
+ retries for hdlc
+
+During initialization the CC1352 FW will be in a loop
+looking for HDLC ACK and FW response is very slow, but currently
+bcfserial driver expects the CC1352 to respond within 5 ms, but the
+CC1352 takes few 100 ms to complete this operation, thus keep the
+retry count to a high value so that the probe failure does not happen
+due to failling the bcfserial_get_device_capabilities() call.This is
+a one-time setup delay during probe() and does not affect performance.
