* Add DEBUG*() macros
This set of macros allows you to write printf-like debugging lines that
automatically check whether a debug is on before printing. This should
eliminate the need for explicit checks in simple cases. For example:
if (SUCH_AND_SUCH_DEBUG_IS_ON) {
zlog_warn(...);
}
Becomes:
DEBUG(warn, such_and_such, ...);
Or, equivalently,
DEBUGE(such_and_such, ...);
The levels passed to DEBUG are expanded into the names of zlog_*
functions, so the same zlog levels are available. There's also a set of
macros that have the level built into them; DEBUGE for errors, DEBUGW
for warnings, etc. Good for brevity.
* Add singular setting macros
Change the 'SET' macros to accept a boolean indicating whether the
provided bits should be set or unset, and map on/off macros to them.
Helps condense code where you already have a boolean condition that
tells you what you want to do as you can avoid writing the branch.

For building dev packages for alpine, we provide a minimal APKBUILD
file and add a configure option for only numeric versions in the
VERSION variable as alpine does not allow non-numeric characters
in the version string.
These changes allow alpine to be built, but don't yet provide a
mechanism to build. Changes to do the build in docker are coming
soon...
Testing done:
Built alpine packages in local docker environment, packages
showed no "dev" in the package name. Also built CentOS packages
with numeric version disabled and the "dev" is still in the package
name.

musl-libc is a lightweight libc used by alpine linux:
https://www.musl-libc.org/
AFAICT, this is the only change to the source needed to get
basic frr support compiling on musl.
Two changes in one patch, get ethhdr from netinet/if_ether.h
and replace the only __caddr_t I could find in the source base
with caddr_t.
Testing done:
Compiled apk packages using a docker environment (patches
coming soon) also compiled redhat and debian using a similar
docker environment (RFC patches for those changes are queued
up too)...

Every place we need to pass around the rule structure
we need to pass around the ifp as well. Move it into
the structure. This will also allow us to notify up

Allow the add/delete to go through a intermediary function in
zebra_pbr.c instead of directly to the underlying os call. This
will allow future refinements to track the data a bit better
so that on shutdown we can delete the rules.

The work_queue_free function free'd up the wq pointer but
did not set it too NULL. This of course causes situations
where we may use the work_queue after it is freed. Let's

Add a ZAPI_ROUTE_REMOVED to the send of the route_notify_owner
Add a ZAPI_ROUTE_REMOVE_FAIL to the send of the route_notify_owner
Add code in sharpd to notice this and to allow it to keep

The buffer size is currently 4k. Increase x4 times to allow for bigger
messages to be sent over the zapi.
The current size sufficient for most cases, but there are a couple
of cases with installing data to the kernel ip rules where we will
quickly hit this 4k size limit. I forsee flowspec getting close
to this limit as well.

When zebra is being configed we allow for static routes
to be entered. This presents a problem for when a vrf
is cli configed but not kernel configed yet.
Modify zebra to notice that when a static route is
entered and either the nexthop vrf or the vrf
is not fully configed, to save that config to the
side.
When vrf's become active( kernel configed ) parse
through the list of saved to the side static routes
and determine if any of them can be installed.
Additionally modify the cli to output the saved
to the side cli, so that we can properly handle
a wr mem.
