ft_fax
Contains a bitmask of the board type and fax features supported on the specified device.
• FT_FAX – specifies that the device has a fax daughterboard
• FT_RS_SHARE – supports fax resource sharing

On Springware boards, if this bit is turned on and the FT_SENDFAX_TXFILE_ASCII
bit (in ft_send) is turned on, then the device supports DSP Fax (also known as Softfax).
On DM3 boards, if the ft_fax field contains the bitmask FT_FAX | FT_VFX40 |
FT_VFX40E | FT_VFX40E_PLUS, then this device supports fax.
ft_front_end
Contains a bitmask of the front-end features supported on the specified device.
On DM3 boards, one or more of the following may be returned:
• FT_ANALOG_CID – returned by the Intel® Dialogic® DMV160LP board
