igb: check timestamp validity
[ Upstream commit f0a03a02 ] Add a couple of checks to make sure timestamping is on and that the timestamp value from DMA is valid. This avoids any functional issues that could come from a misinterpreted time stamp. One of the functions changed doesn't need a return value added because there was no value in checking from the calling locations. While here, fix a couple of reverse christmas tree issues next to the code being changed. Fixes: f56e7bba ("igb: Pull timestamp from fragment before adding it to skb") Fixes: 9cbc948b ("igb: add XDP support") Signed-off-by:Jesse Brandeburg <jesse.brandeburg@intel.com> Tested-by:
