Add the beginnings of a testsuite for tc functionality in the kernel.
These are a series of unit tests that use the tc executable and verify
the success of those commands by checking both the exit codes and the
output from tc's 'show' operation.
To run the tests:
# cd tools/testing/selftests/tc-
Apologies for sending this as one big patch. I've been sitting on this a little
too long, but it's ready and I wanted to get it out.
There are a limited number of tests to start - I plan to add more on a regular
basis.

HW timestamping can only be requested for a packet if the NIC is first
setup via ioctl(SIOCSHWTSTAMP). If this step was skipped, then the igb
driver still allowed TX packets to request HW timestamping. In this
situation, the _IGB_PTP_TX_IN_PROGRESS flag was set and would never

Pass XDP flags to the xdp ndo. This will allow drivers to look
at the mode flags and make decisions about offload.

Hi!
This set adds XDP flag for forcing offload and a attachement mode
for reporting to user space that program has been offloaded. The
nfp driver is modified to make use of the new flags, but also to
adhere to the DRV_MODE flag which should disable the HW offload.
Note that the NFP driver curren
Respect the XDP_FLAGS_HW_MODE. When it's set install the program
on the NIC and skip enabling XDP in the driver.

Extend the XDP_ATTACHED_* values to include offloaded mode.
Let drivers report whether program is installed in the driver
or the HW by changing the prog_attached field from bool to
u8 (type of the netlink attribute).
Exploit the fact that the value of XDP_ATTACHED_DRV is 1,
therefore since all dri
The xdp_prog member of the adapter's data path structure is used
for XDP in driver mode. In case a XDP program is loaded with in
HW-only mode, we need to store it somewhere else. Add a new XDP
prog pointer in the main structure and use that when we need to
know whether any XDP program is loaded,
DRV_MODE means that user space wants the program to be run in
the driver. Do not try to offload. Only offload if no mode
flags have been specified.
Remember what the mode is when the program is installed and refuse
new setup requests if there is already a program loaded in a
different mode. Thi
In preparation of XDP offload flags move the driver setup into
a function. Otherwise the number of conditions in one function
would make it slightly hard to follow. The offload handler may
now be called with NULL prog, even if no offload is currently
active, but that's fine, offload code can hand
Add an installation-time flag for requesting that the program
be installed only if it can be offloaded to HW.
Internally new command for ndo_xdp is added, this way we avoid
putting checks into drivers since they all return -EINVAL on
an unknown command.
