2021-10-05net: bgmac: support MDIO described in DTRafał Miłecki1-1/+5
Check ethernet controller DT node for "mdio" subnode and use it with of_mdiobus_register() when present. That allows specifying MDIO and its PHY devices in a standard DT based way. This is required for BCM53573 SoC support. That family is sometimes called Northstar (by marketing?) but is quite different from it. It uses different CPU(s) and many different hw blocks. One of shared blocks in BCM53573 is Ethernet controller. Switch however is not SRAB accessible (as it Northstar) but is MDIO attached.

2021-10-05net: bgmac: improve handling PHYRafał Miłecki1-12/+21
1. Use info from DT if available It allows describing for example a fixed link. It's more accurate than just guessing there may be one (depending on a chipset). 2. Verify PHY ID before trying to connect PHY PHY addr 0x1e (30) is special in Broadcom routers and means a switch connected as MDIO devices instead of a real PHY. Don't try connecting to it.

2021-10-04net/mlx5: Enable single IRQ for PCI FunctionShay Drory2-8/+19
Prior to this patch the driver requires two IRQs to function properly, one required IRQ for control and at least one required IRQ for IO. This requirement can be relaxed to one as the driver now allows sharing of IRQs, so control and IO EQs can share the same irq. This is needed for high scale amount of VFs.

2021-10-04net/mlx5: Shift control IRQ to the last indexShay Drory5-11/+13
Control IRQ is the first IRQ vector. This complicates handling of completion irqs as we need to offset them by one. in the next patch, there are scenarios where completion and control EQs will share the same irq. for example: functions with single IRQ. To ease such scenarios, we shift control IRQ to the end of the irq array. Signed-off-by: Shay Drory <shayd@nvidia.com> Signed-off-by: Saeed Mahameed <saeedm@nvidia.com>

Refactor sample unoffload to be symmetric to sample offload. Use the existing del_post_rule() to release the post rule. Also mlx5e_tc_sample_unoffload() should not return post_rule which is NULL when post actions are supported. Sample offload works with this NULL because many places of the code use IS_ERR() instead of IS_ERR_OR_NULL() to check rule is valid and when rule is detected as sample offload the code is not using the rule.

2021-10-02ethernet: use eth_hw_addr_set() - castsJakub Kicinski3-3/+3
eth_hw_addr_set() takes a u8 pointer, like other etherdevice helpers. Convert the few drivers which require casts because they memcpy from "endian marked" types. Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>

2021-10-02ethernet: s2io: use eth_hw_addr_set()Jakub Kicinski1-1/+1
Manual conversions because we need to get to the member which is inside an array to have a u8 pointer which eth_hw_addr_set() expects. Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>
