This function is called by the Tx interrupt serivce routine to perform some OS related operations on the SKB before passing it to the upper layers. It mainly checks if the checksum is OK, if so adds it to the SKBs cksum variable, increments the Rx packet count and passes the SKB to the upper layer. If the checksum is wrong, it increments the Rx packet error count, frees the SKB and returns error.
