CVE-2024-42291: ice: Add a per-VF limit on number of FDIR filters
In the Linux kernel, the following vulnerability has been resolved:
ice: Add a per-VF limit on number of FDIR filters
While the iavf driver adds a s/w limit (128) on the number of FDIR filters that the VF can request, a malicious VF driver can request more than that and exhaust the resources for other VFs.
Add a similar limit in ice.
