 Next the Rx processing must be similarly divided into separate "start" and "finish" functions. First modify {{{frame_receive()}}} to immediately return instead of blocking:
 
- we need to perform a similar dissection of the {{{frame_receive()}}} context to quit early before the reception has finished. Note: it is important to return the value {{{FRAME_RX_RET_SKIP_RX_STARTED_RESET}}} from this context to prevent the MAC Low Framework from resetting the PHY while the reception is still ongoing. Replace {{{frame_receive()}}} with the following:

This flag informs the MAC framework that the application is not finishes processing the current Rx event and that the framework should not reset the Rx state, ensuring the {{{finish_frame_receive()}}} below has the opportunity to process the reception once it completes.
