That's still a lot of input errors.
There are a few reasons for these to accumulate:
- Receive ring overrun. Unfortunately, the log message for this is
wrapped in #ifdef WM_DEBUG, so you'll need to tweak the driver and
rebuild the kernel to see the log message.
- Failure to allocate a new receive buffer. When this happens, the
received packet is dropped the its buffer recycled. Again,
unfortunately, this has a debug-only kernel printf associated with it.
- The chip reported some sort of error with the packet. It logs
messages in system log for the following:
- symbol error
- receive sequence error
- CRC error
A carrier extension error or a Rx data error could also occur, but
these are not logged.
