If anyone has any objections, please let me know. ------------------ From: Felix Fietkau [ Upstream commit 04280d0a56be4264720e7b205daaa332c715e5ec ] train_up_high_thres, train_up_rule_rssi and low_traffic_thres were declared as host-native short in a firmware-facing TLV and assigned host-order constants, so on a big-endian host the firmware received byte-swapped rate-adaptation thresholds. Declare them __le16 and convert with cpu_to_le16().
