2020-09-16net: stmmac: Add support to Ethtool get/set ring parametersSong, Yoong Siang1-1/+1
This patch add support to --show-ring & --set-ring Ethtool functions: - Adding min, max, power of two check to new ring parameter's value. - Bring down the network interface before changing the value of ring parameters. - Bring up the network interface after changing the value of ring parameters.

2020-08-23treewide: Use fallthrough pseudo-keywordGustavo A. R. Silva1-2/+2
Replace the existing /* fall through */ comments and its variants with the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary fall-through markings when it is the case.

2020-06-18net: stmmac: selftests: Use struct_size() helper in kzalloc()Gustavo A. R. Silva1-1/+1
Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes. This code was detected with the help of Coccinelle and, audited and fixed manually. Signed-off-by: Gustavo A. R. Silva <gustavoars@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2020-03-23net: sched: rename more stats_typesJakub Kicinski1-2/+2
Commit 53eca1f3479f ("net: rename flow_action_hw_stats_types* -> flow_action_hw_stats*") renamed just the flow action types and helpers. For consistency rename variables, enums, struct members and UAPI too (note that this UAPI was not in any official release, yet).

2020-03-17net: rename flow_action_hw_stats_types* -> flow_action_hw_stats*Jakub Kicinski1-2/+2
flow_action_hw_stats_types_check() helper takes one of the FLOW_ACTION_HW_STATS_*_BIT values as input. If we align the arguments to the opening bracket of the helper there is no way to call this helper and stay under 80 characters. Remove the "types" part from the new flow_action helpers and enum values. Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2020-03-11net: stmmac: selftests: Fix L3/L4 Filtering testJose Abreu1-0/+2
Since commit 319a1d19471e, stmmac only support basic HW stats type for action. Set this field in the L3/L4 Filtering test so that it correctly setups the filter instead of returning EOPNOTSUPP.

Add a new test for TBS feature which is used in ETF scheduler. In this test, we send a packet with a launch time specified as now + 500ms and check if the packet was transmitted on that time frame.

2020-01-13net: stmmac: selftests: Switch to dev_direct_xmit()Jose Abreu1-19/+6
In the upcoming commit for TBS selftest we will need to send a packet on a specific Queue. As stmmac fallsback to netdev_pick_tx() on the select Queue callback, we need to switch all selftests logic to dev_direct_xmit() so that we can send the given SKB on a specific Queue.

2019-12-18net: stmmac: selftests: Needs to check the number of Multicast regsJose Abreu1-0/+4
When running the MC and UC filter tests we setup a multicast address that its expected to be blocked. If the number of available multicast registers is zero, driver will always pass the multicast packets which will fail the test. Check if available multicast addresses is enough before running the tests.

2019-11-06net: stmmac: selftests: Prevent false positives in filter testsJose Abreu1-40/+94
In L2 tests that filter packets by destination MAC address we need to prevent false positives that can occur if we add an address that collides with the existing ones. To fix this, lets manually check if the new address to be added is already present in the NIC and use a different one if so. For Hash filtering this also envolves converting the address to the hash.
