[ Upstream commit 24994513ad13ff2c47ba91d2b5df82c3d496c370 ]
The `devlink -j port show` command output may not contain the "flavour"
key, an example from Ubuntu 22.10 s390x LPAR(5.19.0-37-generic), with
mlx4 driver and iproute2-5.15.0:
{"port":{"pci/0001:00:00.0/1":{"type":"eth","netdev":"ens301"},
"pci/0001:00:00.0/2":{"type":"eth","netdev":"ens301d1"},
"pci/0002:00:00.0/1":{"type":"eth","netdev":"ens317"},
"pci/0002:00:00.0/2":{"type":"eth","netdev":"ens317d1"}}}
This will cause a KeyError exception.
Create a validate_devlink_output() to check for this "flavour" from
devlink command output to avoid this KeyError exception. Also let
it handle the check for `devlink -j dev show` output in main().
Apart from this, if the test was not started because the max lanes of
the designated device is 0. The script will still return 0 and thus
causing a false-negative test result.
Use a found_max_lanes flag to determine if these tests were skipped
due to this reason and return KSFT_SKIP to make it more clear.

tweewide: Fix most Shebang lines2021-05-22T09:40:55+00:00Finn Behrensme@kloenk.de2020-11-23T14:15:33+00:00urn:sha1:6ae514b8a8eb675df9d746693726a72d46f2391d
commit c25ce589dca10d64dde139ae093abc258a32869c upstream.
Change every shebang which does not need an argument to use /usr/bin/env.
This is needed as not every distro has everything under /usr/bin,
sometimes not even bash.

selftests: net: Add port split test2020-07-09T20:15:30+00:00Danielle Ratsondanieller@mellanox.com2020-07-09T13:18:22+00:00urn:sha1:f3348a82e72795ce218264fd00ef5cf5137836a9
Test port split configuration using previously added number of port lanes
attribute.
Check that all the splittable ports are successfully split to their maximum
number of lanes and below, and that those which are not splittable fail to
be split.
Test output example:
TEST: swp4 is unsplittable [ OK ]
TEST: split port swp53 into 4 [ OK ]
TEST: Unsplit port pci/0000:03:00.0/25 [ OK ]
TEST: split port swp53 into 2 [ OK ]
TEST: Unsplit port pci/0000:03:00.0/25 [ OK ]
