Electrical Idle Mask
If set to 1b, disables the check for illegal electrical idle
sequence (such as, eidle ordered set without common mode
and vise versa), and accepts any of them as the correct eidle
0b
sequence.
Note: The specification can be interpreted so that idle
ordered set is sufficient for transition to power management
states. The use of this bit allows an acceptance of such
interpretation and avoids the possibility of correct behavior
to be understood as illegal sequences.
