hex:attribute-name behavior is changed

[Chaigneau, Nicolas]

Hello,


I've just opened an issue that looks very similar, this is probably the same:

> Hi,

> Previously the expansion %{hex:DHCP-Client-Hardware-Address} worked correctly by expanding to the mac address value inside the attribute.
> Now the latest master(#a88b05513956b21ec037383780f9b568eeb49124) is expanding the raw string "DHCP-Client-Hardware-Address" to hex.

> However, %{hex:%{DHCP-Client-Hardware-Address} is working as expected(expands the value inside the attribute).
