T5974: Fix QoS shape bandwidth and ceil calculation for default
The default `bandwidth` and `ceiling` should calculate values based on <tag> bandwidth but currently it gets the value from qos.base `/sys/class/net/{self._interface}/speed` ``` set qos policy shaper SHAPER bandwidth '20mbit' set qos policy shaper SHAPER default bandwidth '95%' set qos policy shaper SHAPER default ceiling '100%' ``` It causes wrong calculations for class `default` i.e 950Mbit for bandwidth (expected 95% of bandwidth, 19Mbit) 1Gbit for ceil (expected 100% of bandwidth, 20Mbit) Gets incorrect values ``` r4# tc class show dev eth1 class htb 1:1 root rate 20Mbit ceil 20Mbit burst 1600b cburst 1600b class htb 1:a parent 1:1 leaf 8053: prio 0 rate 200Kbit ceil 200Kbit burst 1Mb cburst 1600b class htb 1:b parent 1:1 leaf 8054: prio 7 rate 950Mbit ceil 1Gbit burst 15200b cburst 1375b ``` Fix this
