Subject: Re: [PATCH][iproute2] tc/q_htb.c: Fix the MPU value output in 'tc -d class show dev <device_name> ' command
Phil,

Tried building iproute2 (as of tag 4.2) and using the upstream linux kernel (also tag 4.2 - 64291f7db5bd8150a74ad2036f1037e6a0428df2):
~/src/iproute2/tc$ uname -r
4.2.0-040200-generic
~/src/iproute2/tc$ grep -inP 'htb' /boot/config-4.2.0-040200-generic
1331:CONFIG_NET_SCH_HTB=m
~/src/iproute2/tc$ lsmod | grep htb
sch_htb 24576 1
~/src/iproute2/tc$ ./tc -d class show dev eth0
~/src/iproute2/tc$ sudo ./tc qdisc add dev eth0 root handle 1: htb default 12
~/src/iproute2/tc$ sudo ./tc class add dev eth0 parent 1: classid 1:1 htb rate 100kbps ceil 100kbps mpu 256 overhead 64
~/src/iproute2/tc$ tc -d class show dev eth0
class htb 1:1 root prio 0 quantum 10000 rate 800Kbit overhead 64 ceil 800Kbit linklayer ethernet burst 1600b/1 mpu 0b overhead 0b cburst 1600b/1 mpu 0b overhead 0b level 0
~/src/iproute2/tc$ lsmod | grep htb
sch_htb 24576 1
So it looks like the overhead is being set correctly, but the mpu is not, even though the respective kernel module is loaded judging by what I see.
