Subject: [PATCH net-next 2/2] octeontx2-af: debugfs: Add Channel info to RPM map
Display channel info in the RPM map debugfs output.
With this, cat /sys/kernel/debug/cn10k/rvu_pf_rpm_map
would display channel number for each device in addition to
the existing data.
Sample output:
PCI dev RVU PF Func NIX block rpm LMAC CHAN
0002:02:00.0 0x400 NIX0 rpm0 LMAC0 256
