bnxt_en: Synchronize tx when xdp redirects happen on same ring
[ Upstream commit 4f81def272de17dc4bbd89ac38f49b2676c9b3d2 ]
If there are more CPUs than the number of TX XDP rings, multiple XDP
redirects can select the same TX ring based on the CPU on which
XDP redirect is called. Add locking when needed and use static
key to decide whether to take the lock.
Fixes: f18c2b77b2e4 ("bnxt_en: optimized XDP_REDIRECT support")
