net: aquantia: do not pass lro session with invalid tcp checksum
Individual descriptors on LRO TCP session should be checked for CRC errors. It was discovered that HW recalculates L4 checksums on LRO session and does not break it up on bad L4 csum. Thus, driver should aggregate HW LRO L4 statuses from all individual buffers of LRO session and drop packet if one of the buffers has bad L4 checksum.
