Bluetooth: btqcomsmd: Fix rx/tx stats (61a1ecfc) · Commits · 戴 / test

HCI RX/TX byte counters were only incremented when sending ACL packets. To reflect the real HCI traffic, we need to increment these counters on HCI events and HCI commands as well. Increment error counter on rpmsg errors. Signed-off-by:
