The man page and the "fail" example are missing an underscore in the
nf_mark ematch.
eg.
tc filter add dev eth0 parent ffff: basic match 'meta(nfmark gt 24)'
classid 2:4
meta: unknown meta id
... >>meta(nfmark gt 24)<< ...
... meta(>>nfmark<< gt 24)...
Usage: meta(OBJECT { eq | lt | gt } OBJECT)
where: OBJECT := { META_ID | VALUE }
META_ID := id [ shift SHIFT ] [ mask MASK ]
Example: meta(nfmark gt 24)
meta(indev shift 1 eq "ppp")
meta(tcindex mask 0xf0 eq 0xf0)
For a list of meta identifiers, use meta(list).
Illegal "ematch"
meta(list) does correctly show nf_mark and the above test works with
nf_mark.

Update the rt_dsfield file to contain values defined in current RFC.
The days of TOS precedence are gone, even Cisco doesn't refer
to these in the documents.
The real checking is performed later in iplink_modify(..) func which
checks device existence if NLM_F_CREATE flag is set.
Also it fixes the case when impossible to add veth link which was
caused by 9a02651a87 (ip: check for missing dev arg when doing VF rate)
because these devices are not exist yet.

First, the default value for 1-k is documented as being 0, but is
currently being set to 1. (100%). This causes all packets to be dropped
in the good state if 1-k is not explicitly specified. Fix this by setting
the default to 0.
Second, the 1-h option is parsed correctly, however, the kernel is
expecting "h", not 1-h. Fix this by inverting the "1-h" percentage before
sending to and after receiving from the kernel. This does change the
behavior, but makes it consistent with the netem documentation and the
literature on the Gilbert-Elliot model, which refer to "1-h" and "1-k,"
not "h" or "k" directly.
Last, fix a minor formatting issue for the options reporting.

This patch avoids a full link wildump request when the user has specified
a single link. Uses RTM_GETLINK without the NLM_F_DUMP flag.
This helps on a system with large number of interfaces.
This patch currently only uses the link ifindex in the filter.
Hoping to provide a subsequent kernel patch to do link dump filtering on
other attributes in the kernel.
In iplink_get, to be safe, this patch currently sets the answer buffer
size to the max size that libnetlink rtnl_talk can copy. The current api
does not seem to provide a way to indicate the answer buf size.

Consider the following command:
ip tunnel add mode vti remote 12.0.0.1 local 12.0.0.3 ikey 15
i_flags will be GRE_KEY|VTI_ISVTI. So, in order to distinguish between ipip and
vti we have to check just VTI_ISVTI bit, not the equality of i_flags and
VTI_ISVTI.
* Note, that there also was a bug in ip_tunnel/ip_vti, see
commit 7c8e6b9c281(ip_vti: Fix 'ip tunnel add' with 'key' parameters),
https://lkml.org/lkml/2014/6/7/125.
Even patched iproute could be unable to create vti tunnels with non-zero keys.
1) Unpatched iproute2:
[root@vm ~]# ip tunnel show
[root@vm ~]# lsmod | egrep '(ipip|vti)'
[root@vm ~]# ip tunnel add mode vti ikey 1
[root@vm ~]# lsmod | egrep '(ipip|vti)'
ipip 4197 0
tunnel4 1659 1 ipip
ip_tunnel 9295 1 ipip
[root@vm ~]# ip tunnel show
tunl0: ip/ip remote any local any ttl inherit
[root@vm ~]# ip tunnel add mode vti remote 1.2.3.4 ikey 2
[root@vm ~]# ip tunnel show
ipip0: ip/ip remote 1.2.3.4 local any ttl inherit
tunl0: ip/ip remote any local any ttl inherit
[root@vm ~]# lsmod | egrep '(ipip|vti)'
ipip 4197 0
tunnel4 1659 1 ipip
ip_tunnel 9295 1 ipip
# ipip tunnels are created instead of vti
2) Patched iproute2:
[root@vm ~]# ip tunnel show
[root@vm ~]# lsmod | egrep '(ipip|vti)'
[root@vm ~]# ip tunnel add mode vti ikey 1
[root@vm ~]# lsmod | egrep '(ipip|vti)'
ip_vti 5258 0
ip_tunnel 9295 1 ip_vti
[root@vm ~]# ip tunnel show
vti0: ip/ip remote any local any ttl inherit ikey 1 okey 0
ip_vti0: ip/ip remote any local any ttl inherit nopmtudisc key 0
[root@vm ~]# ip tunnel add mode vti remote 1.2.3.4 ikey 2
[root@vm ~]# ip tunnel show
vti0: ip/ip remote any local any ttl inherit ikey 1 okey 0
vti1: ip/ip remote 1.2.3.4 local any ttl inherit ikey 2 okey 0
ip_vti0: ip/ip remote any local any ttl inherit nopmtudisc key 0
# Vti tunnels are created as expected
# * If you have unpatched kernel your vti tunnels will have ikey == okey == 0
Same story exists with ip tunnel show/del with non-zero [io]key: requests are
routed to tunl0 instead of ip_vti0.

This patch adds master dev name from NDA_MASTER netlink attribute
to bridge fdb show output
current iproute2 tries to print 'master' in the output if NTF_MASTER
is present. But, kernel today does not set NTF_MASTER during dump
requests. Which means I have not seen iproute2 bridge cmd print 'master' atall.
This patch overrides the NTF_MASTER flag if NDA_MASTER attribute is present.
Example output:
before this patch:
# bridge fdb show
44:38:39:00:27:ba dev bond2.2003 permanent
44:38:39:00:27:bb dev bond4.2003 permanent
44:38:39:00:27:bc dev bond2.2004 permanent
After this patch:
# bridge fdb show
44:38:39:00:27:ba dev bond2.2003 master br-2003 permanent
44:38:39:00:27:bb dev bond4.2003 master br-2003 permanent
44:38:39:00:27:bc dev bond2.2004 master br-2004 permanent
For comparision with the above, below is the output for NTF_SELF today,
# bridge fdb show
33:33:00:00:00:01 dev eth0 self permanent
01:00:5e:00:00:01 dev eth0 self permanent
33:33:ff:00:01:cc dev eth0 self permanent
If change in output is a concern, 'master' can be put at the end of the fdb
output line or made optional with -d[etails] option.
change from v1 to v2:
use 'bridge' instead of 'master' in fdb show output
change from v2 to v3:
use 'master' instead of 'bridge' in fdb show output
(master could also be a vxlan device)

o "min_tx_rate" option has been added for minimum Tx rate. Hence, for
consistent naming, "max_tx_rate" option has been introduced for maximum
Tx rate.
o Change in v2: "rate" can be used along with "max_tx_rate".
When both are specified, "max_tx_rate" should override.
o Change in v3:
* IFLA_VF_RATE: When IFLA_VF_RATE is used, and user has given only one of
min_tx_rate or max_tx_rate, reading of previous rate limits is done in
userspace instead of in kernel space before ndo_set_vf_rate.
* IFLA_VF_TX_RATE: When IFLA_VF_TX_RATE is used, min_tx_rate is always read
in kernel space. This takes care of below scenarios:
(1) when old tool sends "rate" but kernel is new (expects min and max)
(2) when new tool sends only "rate" but kernel is old (expects only "rate")
o Change in v4 as suggested by Stephen Hemminger:
* As per iproute policy, input and output formats should match. Changing display
of max_tx_rate and min_tx_rate options accordingly.
