46d032d002 tc: sfb: add support for JSON output
Enable proper JSON output for the SFB Qdisc.
Make the output for options "rehash" and "db" explicit.
Use the long double format specifier to print probability values.
Use sprint_time() to print time values.
Also, fix the indentation in sfb_print_opt().

c14f9d92ee treewide: Use addattr_nest()/addattr_nest_end() to handle nested attributes
We have helper routines to support nested attribute addition into
netlink buffer: use them instead of open coding.

Use addattr_nest_compat()/addattr_nest_compat_end() where appropriate.

927e3cfb52 tc: B.W limits can now be specified in %.
This patch adapts the tc command line interface to allow bandwidth limits
to be specified as a percentage of the interface's capacity.

Adding this functionality requires passing the specified device string to
each class/qdisc which changes the prototype for a couple of functions: the
.parse_qopt and .parse_copt interfaces. The device string is a required
parameter for tc-qdisc and tc-class, and when not specified, the kernel
returns ENODEV. In this patch, if the user tries to specify a bandwidth
percentage without naming the device, we return an error from userspace.

d17b136f7d Use C99 style initializers everywhere
This big patch was compiled by vimgrepping for memset calls and changing
to C99 initializer if applicable. One notable exception is the
initialization of union bpf_attr in tc/tc_bpf.c: changing it would break
for older gcc versions (at least <=3.4.6).

Calls to memset for struct rtattr pointer fields for parse_rtattr*()
were just dropped since they are not needed.

The changes here allowed the compiler to discover some unused variables,
so get rid of them, too.
