The direct_qlen command option is used with qdisc operation.
It happened to be implemented in htb_parse_class_opt() which is called
with class operation.

Starting from linux-3.13, we can break the 32bit limitation of
rates on HTB qdisc/classes.

Prior limit was 34.359.738.360 bits per second.

TCA_HTB_DIRECT_QLEN attribute is supported since linux-3.10

HTB classes use an internal pfifo queue, which limit was not reported
by tc, and value inherited from device tx_queue_len at setup time.

With this patch, tc displays the value and can change it.

This iproute2 tc patch is connected to the kernel
- commit 8a8e3d84b17 (net_sched: restore "linklayer atm" handling)

The rate table calculated by tc, have gotten replaced in the kernel
and is no-longer used for lookups.

This happened in kernel release v3.8 caused by kernel
- commit 56b765b79 ("htb: improved accuracy at high rates").
This change unfortunately caused breakage of tc overhead and
linklayer parameters.

Kernel overhead handling got fixed in kernel v3.10 by
- commit 01cb71d2d47 (net_sched: restore "overhead xxx" handling)

Kernel linklayer handling got fixed in kernel v3.11 by
- commit 8a8e3d84b17 (net_sched: restore "linklayer atm" handling)

The linklayer fix introduced a struct change, that allow the linklayer
attribute to be transferred between tc and kernel. This patch make use
of this linklayer attribute.

The linklayer setting is transfer to the kernel. And linklayer
setting received from the kernel is printed with a prefixed
"linklayer" when listing current configuration. The default
TC_LINKLAYER_ETHERNET is only printed in detailed output mode.

"tc class show dev ..." omits the overhead attribute for HTB.

After patch I have :

Introducing the function that does the ATM cell alignment, and
modifying tc_calc_rtable() to use this based upon a linklayer

Modified from original to use constants from atm.h and

Change tc_calc_rtable() to take a tc_ratespec struct as an
argument. (cell_log still needs to be passed on as a parameter,
because -1 indicate that the cell_log needs to be computed by the
function.).

[IPROUTE]: Introduce tc_calc_xmitsize and use where appropriate

Add tc_calc_xmitsize() as complement to tc_calc_xmittime(), which calculates
the size that can be transmitted at a given rate during a given time.

Replace all expressions of the form "size = rate*tc_core_tick2usec(time))/1000000"
by tc_calc_xmitsize() calls.
