Just a quick question on the Pin Assignments in Mirror Mode.
I understand "Mirror" mode remaps the PHYs MDI pins to correlate to a mirrored RJ-45 connector.
[1]
Section 8.4.6.6 Mirror Mode from the DP83867IR datasheet has two tables - Mirror Port Configurations for MDI Modes (MII and GMII)
Assuming the RJ-45 connector is flipped, I see the DP83867IR pin mappings changing as follows.
(i.e. TD_P_A (A+) becomes TD_M_D (D-) when Mirrored = Enabled)
Is my understanding/pin mapping as shown in the above image accurate?

Again, regarding the same p45 tables discussing Mirror Port Configurations.
They mention MDIX configurations being supported as well.
I understand MDIX is crossing A/B and C/D(GigE) of MDI to the Connector.
If so, then why does the Datasheet list the same configuration for both MDI and MDIX?
If you refer to my attached image (above) I have listed the supposed MDIX Mirrored config in Blue.
Are the p45 tables incorrect? Or are they indicating the default MDIX pin assign before the Auto-MDIX negotiation described in 8.4.3.9 Auto-MDIX Resolution on p41?
