2011-11-28transceiver52M: bump critial errors to ALERT levelkurtis.heimerl3-6/+8
Device errors regarding properties such as sample rate or frequency tuning are almost always fatal and lead to the common error "assuming TRX is dead". Make sure that these errors are clearly presented to the user.

2011-11-28transceiver, uhd: exit informatively if no devices are foundkurtis.heimerl1-4/+11
Perform a UHD device search before constructing the object, and inform the user if no device is found. No device found is the most common reason for the transceiver to fail with the dreaded error "assuming TRX is dead".

2011-11-28transceiver, uhd: runtime check for setting master clock ratekurtis.heimerl1-0/+11
Before setting the master clock rate, make sure that the device is capable of being set. For now, assume that devices that operate with default clock rates above 64 MHz, specifically USRP2/N200/N210, cannot be set at 52 MHz. Inform the user that these devices can be used with the compile time option of host based resampling.

2011-11-26transceiver, resamp: enlarge transmit resampler output bufferkurtis.heimerl1-2/+10
It was possible to reach a state where a resampled burst would overrun the transmit output buffer and corrupt the global allocated signal vectors. The result was a segmentation fault when attempting to access heap allocated signal vectors since the pointers were garbage. Whether the segfault occured or not appears to depend on the memory location of the signal vector pointers, since it does not occur on all systems. Double buffer size to accomodate an incoming burst plus up to a full chunk that may be remaining from the previous resampling operation.

2011-11-26transceiver, resamp: insert missing filter valueskurtis.heimerl4-5/+87
With transceiver integration, the resampling filter files were dropped. This created a working resampling implementation for the USRP2 / N200, but with spectrum irregulaties that likely caused issues at longer range operation. Simply reinsert the filter files and modify the filter initialization to use them.

2011-11-26uhd: increase initial transmit transport latencykurtis.heimerl1-1/+1
For network based devices (USRP2, N200, etc.), increase the latency from 2 to 3 frames, which effectively buffers more samples on the host in front of the Ethernet interface. USB devices (USRP1 and B100) utilize an adaptive mechanism so they are less effected by this value.

2011-11-26transceiver: make the transmit drive loop bus dependentkurtis.heimerl5-25/+58
With the introduction of the B100, there is USB support using UHD devices. The characteristics of the trasmit side burst submissions are more reflective of the bus type than the device or driver. Use a fixed latency interval for network devices and the adaptive underrun approach for USB devices - regardless of driver or device type. The GPMC based transport on the E100 appears unaffected by either latency scheme, which defaults to network.

2011-11-26transceiver: reinsert digital gain scalingkurtis.heimerl2-6/+26
Commit e161523c (transceiver: simplify transmit power control) changed transmit gain control to RF setting only. This was appropriate for a WBX board with 25 dB of gain control, but inappropriate for an RFX with fixed transmit gain. RFX boards will regain the ability to set transmit attenuation. Since gain is set on the RF side first, reintroducing digital gain settings should have limited overall effect on non-RFX daughterboards.

Receive buffer flush should continue to read until either the desired number of packets has been read or timeout, which means that the buffer has been emptied.

Transmit tuning was primarily setup for side A only. Some boards - WBX - would still tune with improper channel arguments, though receiver performance was disrupted.

2011-11-26transceiver: fix energy threshold bugkurtis.heimerl1-0/+3
If no bursts were received over a long enough duration then the threshold would roll into negative territory. The energy detection is based on a comparison with the squared threshold, so all handsets would become effectively barred after a certain period of inactivity. In theory, this bug also exists in the mainline tree, but there the daughterboard receive gain is fixed at max, which always allows the ADC to generate sufficient noise to trigger the energy dectector and keep the system in a valid steady state. To fix, simply add a negative value check like those already in place for other locations.
