utilities: Add the ovs_show_fdb command to gdb
...
This adds the ovs_show_fdb command:
Usage: ovs_show_fdb {<bridge_name> {dbg} {hash}}
<bridge_name> : Optional bridge name, if not supplied FDB summary
information is displayed for all bridges.
dbg : Will show structure address information
hash : Will display the forwarding table using the hash
table, rather than the rlu list.

Utilities: Add the simap and netdev_provider dump commands to gdb

This changes add two additional gdb commands:
- ovs_dump_netdev_provider
- ovs_dump_ovs_list <struct simap *>
Here are some examples of their output:

This change adds the ovs_dump_dp_provider command, which allows
dumping of all the registered registered_dpif_class structures.
In addition it has some small internal cleanups.

utilities: Add gdb debug commands to dump lists and pmd info
...
Adds back-end support for walking ovs cmaps, and the following
commands to the gdb script:
- Dump all poll_thread info added to a specific struct dp_netdev*.
Usage: ovs_dump_dp_netdev_poll_threads <struct dp_netdev *>
- Dump all nodes of an ovs_list:
Usage: ovs_dump_ovs_list <struct ovs_list *> {[<structure>] [<member>] {dump}]}
For example dump all the none quiescent OvS RCU threads:
(gdb) ovs_dump_ovs_list &ovsrcu_threads
(struct ovs_list *) 0x7f2a14000900
(struct ovs_list *) 0x7f2acc000900
(struct ovs_list *) 0x7f2a680668d0
This is not very useful, so please use this with the container_of mode:
(gdb) ovs_dump_ovs_list &ovsrcu_threads 'struct ovsrcu_perthread' list_node
(struct ovsrcu_perthread *) 0x7f2a14000900
(struct ovsrcu_perthread *) 0x7f2acc000900
(struct ovsrcu_perthread *) 0x7f2a680668d0
Now you can manually use the print command to show the content, or use the
dump option to dump the structure for all nodes:
(gdb) ovs_dump_ovs_list &ovsrcu_threads 'struct ovsrcu_perthread' list_node dump
(struct ovsrcu_perthread *) 0x7f2a14000900 =
{list_node = {prev = 0xf48e80 <ovsrcu_threads>, next = 0x7f2acc000900}, mutex...
(struct ovsrcu_perthread *) 0x7f2acc000900 =
{list_node = {prev = 0x7f2a14000900, next = 0x7f2a680668d0}, mutex ...
(struct ovsrcu_perthread *) 0x7f2a680668d0 =
{list_node = {prev = 0x7f2acc000900, next = 0xf48e80 <ovsrcu_threads>}, ...

utilities: Add some GDB macros for ovs-vswitchd
...
This commit adds basic GDB macro's for ovs-vswitchd:
- ovs_dump_bridge [ports|wanted]
- ovs_dump_bridge_ports <struct bridge *>
- ovs_dump_dp_netdev [ports]
- ovs_dump_dp_netdev_ports <struct dp_netdev *>
- ovs_dump_netdev
These dump functions show limited info, but you can simply cut/paste
the address and get the full structure info. For example:
(gdb) ovs_dump_netdev
(struct netdev *) 0x555771ed89e0: name = ovs-netdev , auto_classified = false, netdev_class = 0x5557714413c0 <netdev_tap_class>

(struct netdev *) 0x555771fc9660: name = vnet0 , auto_classified = true , netdev_class = 0x555771445e00 <netdev_linux_class>
(struct netdev *) 0x555771fc78d0: name = virbr0 , auto_classified = true , netdev_class = 0x555771445e00 <netdev_linux_class>

(gdb) p *((struct netdev *) 0x7fbefffb5540)
$1 = {name = 0x555771ecef70 "dpdk0", netdev_class = 0x5557714419e0 <dpdk_class>, auto_classified = false, mtu_user_config = true, ref_cnt = 2, change_seq = 12,
