[PATCH] ixgb: fix tx unit hang - properly calculate desciptor count
There were some tso bugs that only showed up with heavy load and 16kB pages that this patch fixes by making the driver's internal use count of descriptors match the count that it was estimating it needed using the DESC_NEEDED macro. This bug caused NETDEV_WATCHDOG resets aka tx timeouts.
