netvsc.rst: is XDP_REDIRECT still actually unsupported?

Hi Haiyang,

Documentation/networking/device_drivers/ethernet/microsoft/netvsc.rst
still says "XDP_REDIRECT action is not yet supported," but
netvsc_run_xdp() in netvsc_bpf.c seems to handle it fully -- calls
xdp_do_redirect(), tracks stats, and netvsc_drv.c advertises
NETDEV_XDP_ACT_REDIRECT. This looks like it's been true since your
commit 1cb9d3b6185b.

Is the doc just stale, or is there a caveat I'm missing? Happy to
send a one-line fix, or feel free to just tweak it yourself if
that's quicker.

Thanks,
Christian
