Bug Description
The ROHC library 1.6.x does not support the feedback option LOSS. Option LOSS is defined in RFC 3095, section 5.7.6.9 (https:/
The LOSS option allows the decompressor to report the largest
observed number of packets lost in sequence. This information MAY be
used by the compressor to adjust the size of the reference window
used in U- and O-mode.
+---
| Opt Type = 7 | Opt Len = 1 |
+---
| longest loss event (packets) |
+---
The decompressor MAY choose to ignore the oldest loss events. Thus,
the value reported may decrease. Since setting the reference window
too small can reduce robustness, a FEEDBACK packet carrying a LOSS
option SHOULD also carry a CRC option. The compressor MAY choose to
ignore decreasing loss values.
