Section 10.14 says:
The value field of the AT_MAC attribute contains two reserved bytes followed by a keyed message authentication code (MAC). The MAC is | calculated over the whole EAP packet and concatenated with optional message-specific data, with the exception that the value field of the MAC attribute is set to zero when calculating the MAC.
It should say:
The value field of the AT_MAC attribute contains two reserved bytes followed by a keyed message authentication code (MAC). The MAC is | calculated over the whole EAP packet, concatenated with optional message-specific data, with the exception that the value field of the MAC attribute is set to zero when calculating the MAC.
Notes:
"The MAC is calculated ... and concatenated ..."
could easily be misunderstood.
From the context it can be concluded that the potential ambiguity
should be resolved and clarified by omitting the word 'and',
and replacing it by a comma.
