If there is a PHY change on a connection it may happen that effective RX and TX time changes also. That change is applied after an instant. Implemented handling of effective time calculation is based on the maximum PDU length, new PHY and local (default) maximum TX or RX time. The maximum TX value is set to default one that corresponds to PHY 1M during the Controller initialization. It can be updated by host to other value. By default Zephyr Host updates it to max possible TX time for all supported PHYs. If PHY CODED is enabled, it is the longest possible TX duration 17040 us. The maximum RX value is set to default during connection creation. In case of use of legacy advertising, the value is also related with PHY 1M. It can be updated by data length extension procedure. If the maximum RX value is set to some value and there is a change of a PHY to one that requires more time to send a PDU with the same length, then the maximum RX value is wrongly calculated. Function pu_calc_eff_time returns a value that is the default_time argument. The problem is that the default_time should be adjusted to new maximum RX time required for a new PHY. To solve that there should be an evaluation of a new maximum RX and TX time based on new PHY. The commit adds missing evaluation. The problem occurred in DF tests that check collision mitigation between PHY update control procedure and CTE request control procedure. There was missing CONFIG_BT_CTLR_PHY_CODED option in CTE request unit tests. The code was working because the ULL implementation of PHY change control procedure does not verify if PHY CODED is supported. When missing support was enabled, tests showed wrong evaluation of maximum RX time. It also unveiled error in CTE request unit tests implementation. The default_tx_time was set to wrong value 2120 us as if PHY CODED was not supported. To fix it, the value was changed to PDU_DC_PAYLOAD_TIME_MAX_CODED. There was also added a mock for a feature exchange procedure done during unit tests setup step. That allows to correctly calculate maximum TX time by ull_dle_max_time_get function.
