      net: usb: ax88179_178a: restore state on resume · c4bf747c
      Justin Chen authored
      The hardware state was only partially restored, which meant certain
      functionality was broken on resume. Do a full HW reset on resume to
      fix this.

      net: usb: ax88179_178a: clean up pm calls · 843f9205
      Justin Chen authored
      Instead of passing in_pm flags all over the place, use the private
      struct to handle in_pm mode.

      net: usb: ax88179_178a: remove redundant init code · 9718f9ce
      Justin Chen authored
      Bind and reset are basically doing the same thing. Remove the duplicate
      code and have bind call into reset.

      Bluetooth: btusb: Detect if an ACL packet is in fact an ISO packet · 14202eff
      Luiz Augusto von Dentz authored
      Fix up the packet type if ISO packets are sent over the bulk endpoint.
      
      Note: This is a stopgap since the Bluetooth specification currently
      doesn't define any endpoint to transport ISO packets.

      Bluetooth: ISO: Add broadcast support · f764a6c2
      Luiz Augusto von Dentz authored
      This adds broadcast support for BTPROTO_ISO by extending the
      sockaddr_iso with a new struct sockaddr_iso_bc where the socket user
      can set the broadcast address when receiving, the SID and the BIS
      indexes it wants to synchronize.
      
      When using BTPROTO_ISO for broadcast the roles are:
      
      Broadcaster -> uses connect with address set to BDADDR_ANY:
      > tools/isotest -s 00:00:00:00:00:00
      
      Broadcast Receiver -> uses listen with address set to broadcaster:
      > tools/isotest -d 00:AA:01:00:00:00
