dvblast returns ioctl errors when dvblastctl is used to get front-end statistics

[mvandenbroecke]

Seen with latest dvblast version 3.4.

Example to reproduce:
First start dvblast:
dvblast -u -d 127.0.0.1:25000 -f 12100000 -s 27500000 -m psk_8 -n 0 -a 0 -r /tmp/dvblast.sock
Next launch dvblastctl:
dvblastctl -r /tmp/dvblast.sock -x xml fe_status

During execution of dvblastctl, dvblast throws the following errors and no signal strength, SNR and BER values are returned:
error: ioctl FE_READ_BER failed (Operation not supported)
error: ioctl FE_READ_SIGNAL_STRENGTH failed (Operation not supported)
error: ioctl FE_READ_SNR failed (Operation not supported)

Looks like deprecated kernel calls are used in "dvb_FrontendStatus", see:

Will this be corrected ?
Thanks for any comment!
