sw test tool: Fix MAC addresses used in tests
IEEE 802.3-2012 (3.2.3 Address fields) says:
b) The first bit (LSB) shall be used in the Destination Address field as an address type designation bit
to identify the Destination Address either as an individual or as a group address. If this bit is 0, it
shall indicate that the address field contains an individual address. If this bit is 1, it shall indicate that
the address field contains a group address that identifies none, one or more, or all of the stations
connected to the LAN. In the Source Address field, the first bit is reserved and set to 0.
c) The second bit shall be used to distinguish between locally or globally administered addresses. For
globally administered (or U, universal) addresses, the bit is set to 0. If an address is to be assigned
locally, this bit shall be set to 1. Note that for the broadcast address, this bit is also a 1.
This patch fixes MAC addresses used in tests as follows:
- set the first bit to 0
- set the second bit to 1
