Hello
My main goal is to improve logging from
[ 0.796804] stmmaceth 1c50000.ethernet: no reset control found
[ 0.802635] Ring mode enabled
[ 0.805713] No HW DMA feature register supported
[ 0.810239] Normal descriptors
[ 0.813577] TX Checksum insertion supported
[ 23.615074] eth0: device MAC address aa:65:84:d5:a3:58
[ 23.704326] RX IPC Checksum Offload disabled
[ 23.704349] No MAC Management Counters available
to that:
[ 0.788147] sun7i-dwmac 1c50000.ethernet (unnamed net_device)
(uninitialized): no reset control found
[ 0.797400] sun7i-dwmac 1c50000.ethernet (unnamed net_device)
(uninitialized): Ring mode enabled
[ 0.806211] sun7i-dwmac 1c50000.ethernet (unnamed net_device)
(uninitialized): No HW DMA feature register supported
[ 0.816658] sun7i-dwmac 1c50000.ethernet (unnamed net_device)
(uninitialized): Normal descriptors
[ 0.825522] sun7i-dwmac 1c50000.ethernet (unnamed net_device)
(uninitialized): TX Checksum insertion supported
[ 12.971725] sun7i-dwmac 1c50000.ethernet eth0: device MAC address
3e:62:18:6f:c7:f4
[ 13.056902] sun7i-dwmac 1c50000.ethernet eth0: RX IPC Checksum Offload
disabled
[ 13.056929] sun7i-dwmac 1c50000.ethernet eth0: No MAC Management Counters
available
But by using the netdev_ functions the first five lines are not "pretty" with
the "(unnamed net_device) (uninitialized)"
Could I switch back do dev_xxx since they are "early device logging" and so
make it prettier ?
Best regards
