# Tests of DL_RESET_REQ, DL_RESET_IND
|
|
# Tested:
|
|
# 1) Valid RESET while stream in state DL_DATAXFER
|
|
# 2) Error conditions: DL_OUTSTATE for DL_RESET_REQ, DL_RESET_ RES
|
|
# 3) Send RESET, other side sends a DISCONNECT_REQ (from state
|
|
# DL_PROV_RESET_PENDING)
|
|
# 4) Send RESET, then send DISCONNECT_REQ (from state
|
|
# DL_USER_RESET_PENDING) other side should see DL_RESET_IND,
|
|
# then DL_DISCONNECT_IND
|
|
# 5) Send RESET, but it never gets acknowledged. Should receive
|
|
# a DL_DISCONNECT_IND
|
|
