Virtual network devices (ipvlan, macvlan, bonding) can enter legitimate
transmit recursion when combined with packet forwarding configurations
such as IPVS NAT.  The existing XMIT_RECURSION_LIMIT (8) in
__dev_queue_xmit() detects and breaks these loops, but the allowed
depth is too high for KASAN-instrumented kernels: each recursion level
consumes significantly more stack due to KASAN inline instrumentation,
and the cumulative usage overflows the kernel stack before the limit
fires.
