e1000: cleanup process_tx_desc
Coverity complains about two overruns in process_tx_desc(). The complaints are false positives, but we might as well eliminate them. The problem is that "hdr" is defined as an unsigned int, but then used to offset an array of size 65536, and another of size 256 bytes. hdr will actually never be greater than 255 though, as it's assigned only once and to the value of tp->hdr_len, which is an uint8_t. This patch simply gets rid of hdr, replacing it with tp->hdr_len, which makes it consistent with all other tp member use in the function. v2: - also cleanup coding style issues in the touched lines Signed-off-by: NAndrew Jones <drjones@redhat.com> Signed-off-by: NMichael S.
