Darron Broad 6639f1e060 V4L/DVB (9917): cx24116: change to ALGO_HW
Slow tuning, EG:

> szap-s2 -r -c 39.FTATV "1=Pgm1;Net1"
reading channels from file '39.FTATV'
zapping to 3 '1=Pgm1;Net1':
delivery DVB-S, modulation QPSK

vpid 0x0200, apid 0x0300, sid 0x0001
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'

Appears to be resolved by dropping zig-zag tuning and relying on
hardware only:

> szap-s2 -r -c 39.FTATV "1=Pgm1;Net1"
reading channels from file '39.FTATV'
zapping to 3 '1=Pgm1;Net1':
delivery DVB-S, modulation QPSK
sat 0, frequency 11140 MHz V, symbolrate 1425000, coderate 5/6, rolloff 0.35
vpid 0x0200, apid 0x0300, sid 0x0001
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
status 01 | signal ff80 | snr 0000 | ber 00000000 | unc 00000000 |
status 1f | signal ff80 | snr c199 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
status 1f | signal c040 | snr c199 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
status 1f | signal ff80 | snr c199 | ber 00000000 | unc 00000000 | FE_HAS_LOCK

Tuning to a weaker channel shows that the hardware recovers sync:

status 03 | signal fd40 | snr 5000 | ber 00000000 | unc 00000000 |
status 1f | signal fe40 | snr 5000 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
status 03 | signal fd80 | snr 5000 | ber 00000000 | unc 00000000 |
status 01 | signal fd80 | snr 4e66 | ber 00000000 | unc 00000000 |
status 1f | signal fe40 | snr 5000 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
status 03 | signal fe40 | snr 5000 | ber 00000000 | unc 00000000 |
status 01 | signal fd80 | snr 0000 | ber 00000000 | unc 00000000 |
status 1f | signal fe40 | snr 5199 | ber 00000000 | unc 00000000 | FE_HAS_LOCK

Also, tuning, moving the dish and then restoring the dish also retunes.
