net: ethernet: oa_tc6: Improve the error recovery
In the Linux kernel, the following vulnerability has been resolved: net: ethernet: oa_tc6: Improve the error recovery When oversubscribed traffic causes lot of buffer overflow errors, probably due to loss of data chunks, driver fails to find a data chunk with end_valid bit set, before it runs out of sk buffer space. As a result, assert is seen during skb_put. Now, check is made if skb buffer has enough tailroom for the incoming data before accepting. If there is no room, current frame is abandoned and it will start looking for a data chunk with start_valid bit, that is a new frame. SK buffer allocation error is considered as recoverable error. rx_buf_overflow flag is too specific and no longer the only condition this flag is used for. Therefore it is renamed as wait_until_start_valid. This is more appropriate as this flag is used to look for the next data chunk with SV bit set, after failures like buffer overflow, buffer allocation failure, skb pointer validity besides buffer overflow error. Not writing to status0 if it reads 0.
