tsnep: Use page pool for RX

2022-09-30T10:32:27Z

Use page pool for RX buffer handling. Makes RX path more efficient and is required prework for future XDP support. Signed-off-by: Gerhard Engleder Signed-off-by: David S. Miller

tsnep: Add EtherType RX flow classification support

2022-09-30T10:32:27Z

Received Ethernet frames are assigned to first RX queue per default. Based on EtherType Ethernet frames can be assigned to other RX queues. This enables processing of real-time Ethernet protocols on dedicated RX queues. Add RX flow classification interface for EtherType based RX queue assignment.

tsnep: Support multiple TX/RX queue pairs

2022-09-30T10:32:26Z

Support additional TX/RX queue pairs if dedicated interrupt is available. Interrupts are detected by name in device tree. Signed-off-by: Gerhard Engleder Signed-off-by: David S. Miller

tsnep: Move interrupt from device to queue

2022-09-30T10:32:26Z

For multiple queues multiple interrupts shall be used. Therefore, rework global interrupt to per queue interrupt. Every interrupt name shall contain interface name and queue information. To get a valid interface name, the interrupt request needs to by done during open like in other drivers. Additionally, this allows the removal of some initialisation checks in the interrupt handler.

net: drop the weight argument from netif_napi_add

2022-09-29T01:57:14Z

We tell driver developers to always pass NAPI_POLL_WEIGHT as the weight to netif_napi_add(). This may be confusing to newcomers, drop the weight argument, those who really need to tweak the weight can use netif_napi_add_weight().

tsnep: Record RX queue

2022-08-22T12:56:37Z

Other drivers record RX queue so it should make sense to do that also. Signed-off-by: Gerhard Engleder Signed-off-by: David S. Miller

tsnep: Support full DMA mask

2022-08-22T12:56:37Z

DMA addresses up to 64bit are supported by the device. Configure DMA mask according to the capabilities of the device. Signed-off-by: Gerhard Engleder Signed-off-by: David S. Miller

tsnep: Improve TX length handling

2022-08-22T12:56:37Z

TX length can by calculated more efficient during map and unmap of fragments. Another reason is that, by moving TX statistic counting to tsnep_tx_poll() it can be used there for XDP too. Signed-off-by: Gerhard Engleder Signed-off-by: David S. Miller

tsnep: Add loopback support

2022-08-22T12:56:37Z

Add support for NETIF_F_LOOPBACK feature. Loopback mode is used for testing. Signed-off-by: Gerhard Engleder Signed-off-by: David S. Miller

tsnep: Fix TSNEP_INFO_TX_TIME register define

2022-08-22T12:56:37Z

Fixed register define is not used, but register definition shall be kept in sync. Fixes: 403f69bbdbad ("tsnep: Add TSN endpoint Ethernet MAC driver") Signed-off-by: Gerhard Engleder Signed-off-by: David S. Miller
