Describe the bug
CCM during on-the-fly decryption of a received packet starts decryption
when Radio triggers EVETNS_ADDRESS. In case there is possibility a
packet may include Constant Tone Extension, on-the-fly parsing of a
received packet for CTEInfo is enabled.
If there is a PHY 1M enabled the Radio stores received bits with a delay,
that is equal to time required to receive 3 bits. That causes a MIC verification
to fail.
CCM TASKS_CRYPT related with packet decryption should be delayed by the
time the Radio needs to store received data.
To Reproduce
direction_finding_central
anddirection_finding_peripheral
samples.Expected behavior
Connection is maintained
Impact
Low, related with DF only.
