I missed that there was a net-next rebase and ended up sending a T-b to
v11 instead of here ([1], [2]), sorry about that.

To give more details on my testing around this specific patch since the

'snps,route-multi-broad' across several different boots and verified
that interrupts showed for all TX/RX channels in /proc/interrupts.
