From 353a0249c3f60365c55d53e2d068de4f43669a22 Mon Sep 17 00:00:00 2001 From: Brian Gix Date: Wed, 27 Oct 2021 16:58:46 -0700 Subject: Bluetooth: hci_sync: Convert MGMT_OP_SET_FAST_CONNECTABLE This creates a synchronized Write Fast Connectable call and attaches it to the MGMT_OP_SET_FAST_CONNECTABLE management opcode.
