Re: CRC errors with gem(4)

Hi,

I should have pointed out that the "ethertype Unknown" packets always start:

  20f7 8e80 0003 wwxx yyzz 0800 ba68 354a
  0800 4500

instead of:

  0800 20f7 8e80 0003 ba68 354a 0800 4500

The destination MAC address (0800 20f7 8e80) is in bytes 10, 11, 0, 1, 2, 3.

The source MAC address is (0003 ba68 354a) in bytes 4, 5, 12, 13, 14, 15

Bytes 6-9 appear to be either parts of the data (3738 393a in this case)
or sometimes 0000 0000.

The IP and TCP parts of the mangled packets are sometimes intact, sometimes
part zeros.

Thanks,

J
