* xMiiPhyTxReceiver.vhd

Do you concur that all of these should be updated?

They pass all my tests – but only because they all have the same issue.

I have updated these and pushed them to the dev branch of OSVVM.

I have seen this issue before when the optional parameter is type integer, but never with type boolean.
