![]() Avoid a loss of synchronisation of the Ethernet Data header 32-bit word due to a failure to get a netdev socket buffer. The ASIX RX handling algorithm returned 0 upon a failure to get an allocation of a netdev socket buffer. This causes the URB processing to stop which potentially causes a loss of synchronisation with the Ethernet Data header 32-bit word. Therefore, subsequent processing of URBs may be rejected due to a loss of synchronisation. This may cause additional good Ethernet frames to be discarded along with outputting of synchronisation error messages. Implement a solution which checks whether a netdev socket buffer has been allocated before trying to copy the Ethernet frame into the netdev socket buffer. But continue to process the URB so that synchronisation is maintained. Therefore, only a single Ethernet frame is discarded when no netdev socket buffer is available.
