CVE-2026-68321: net: txgbe: fix FDIR filter leak on remove
In the Linux kernel, the following vulnerability has been resolved:
net: txgbe: fix FDIR filter leak on remove
Perfect FDIR filters can be added while the interface is down and are kept on the software list for later restore. unregisternetdev() only calls ndostop when the device is up, so txgbefdirfilterexit() in txgbeclose() is skipped in that case and the filters are leaked on driver remove. Free the filter list from txgberemove() as well.
