CVE-2026-74317: ixgbe: do not configure xps for XDP queues
In the Linux kernel, the following vulnerability has been resolved:
ixgbe: do not configure xps for XDP queues
netifsetxpsqueue() should not be called for an XDP Tx queue, since such queues are not netdev-exposed. On systems with number of CPUs >=64, on E610 adapter, netdev is configured with maximum number queue pairs being 63 (due to MSI-X assignment), but configuring XDP results in 64 XDP queues.
So, during XDP program load, when netifsetxpsqueue() is called for the last XDP queue, we get a WARNING with a call trace and KASAN report afterwards (if enabled).
