net: mana: Fix oversized sge0 for GSO packets

2023-10-05T09:45:06Z

Handle the case when GSO SKB linear length is too large. MANA NIC requires GSO packets to put only the header part to SGE0, otherwise the TX queue may stop at the HW level. So, use 2 SGEs for the skb linear part which contains more than the packet header.

net: mana: Annotate struct hwc_dma_buf with __counted_by

2023-10-02T18:24:54Z

Prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). As found with Coccinelle[1], add __counted_by for struct hwc_dma_buf. [1] https://github.com/kees/kernel-tools/blob/trunk/coccinelle/examples/counted_by.cocci Cc: Long Li Cc: Ajay Sharma Cc: "K. Y.

net: mana: Add page pool for RX buffers

2023-08-06T07:36:06Z

Add page pool for RX buffers for faster buffer cycle and reduce CPU usage. The standard page pool API is used. With iperf and 128 threads test, this patch improved the throughput by 12-15%, and decreased the IRQ associated CPU's usage from 99-100% to 10-50%.

net: mana: Configure hwc timeout from hardware

2023-08-04T08:02:55Z

At present hwc timeout value is a fixed value. This patch sets the hwc timeout from the hardware. It now uses a new hardware capability GDMA_DRV_CAP_FLAG_1_HWC_TIMEOUT_RECONFIG to query and set the value in hwc_timeout.

RDMA/mana_ib: Use v2 version of cfg_rx_steer_req to enable RX coalescing

2023-06-01T15:52:01Z

With RX coalescing, one CQE entry can be used to indicate multiple packets on the receive queue. This saves processing time and PCI bandwidth over the CQ. The MANA Ethernet driver also uses the v2 version of the protocol. It doesn't use RX coalescing and its behavior is not changed.
