Subject: [PATCH BlueZ v3 0/8] tests: add TX timestamping tests

Add tests for TX timestamping

v3:
- BT_NO_ERRQUEUE_POLL experimental flag enable in tests
- Drop tester cmdline patch as it's unrelated

v2:
- L2CAP LE Client tests
- SCO TX timestamping test
- Fix emulator bthost L2CAP LE credits send/recv
- Fix emulator SCO send pkts
- BT_NO_ERRQUEUE_POLL test
- Tester command-line option -n

Pauli Virtanen (8):
lib: add BT_SCM_ERROR and BT_NO_ERRQUEUE_POLL
iso-tester: Add tests for TX timestamping
l2cap-tester: Add test for TX timestamping
btdev: set nonzero SCO mtu & max pkt
sco-tester: add TX timestamping test
bthost: handle client L2CAP conn in LE credit based mode
l2cap-tester: add tests for LE Client read/write/tx-timestamping
iso-tester: add test for BT_NO_ERRQUEUE_POLL

Subject: [PATCH BlueZ v3 6/8] bthost: handle client L2CAP conn in LE credit based mode

Allow bthost hooks to receive data from L2CAP LE credit based
connections. Handle LE credit header when receiving, and reassemble
received SDU.

Handle L2CAP LE credit header also in bthost_send_cid.
