ionic: Add XDP_REDIRECT support

2024-02-16T08:48:08Z

The XDP_REDIRECT packets are given to the XDP stack and we drop the use of the related page: it will get freed by the driver that ends up doing the Tx. Because we have some hardware configurations with limited queue resources, we use the existing datapath Tx queues rather than creating and managing a separate set of xdp_tx queues.

ionic: Add XDP_TX support

2024-02-16T08:48:08Z

The XDP_TX packets get fed back into the Rx queue's partnered Tx queue as an xdp_frame. Co-developed-by: Brett Creeley Signed-off-by: Brett Creeley Signed-off-by: Shannon Nelson Reviewed-by: Jacob Keller Signed-off-by: David S. Miller

ionic: add initial framework for XDP support

2024-02-16T08:48:08Z

Set up the basics for running Rx packets through XDP programs. Add new queue setup and teardown steps for adding/removing an XDP program, and add the call to run the XDP on a packet. The XDP frame size needs to be the MTU plus standard ethernet header, plus head room for XDP scribblings and tail room for a struct skb_shared_info. Also, at this point, we don't support XDP frags, only a single contiguous Rx buffer. This means that our page splitting is not very useful, so when XDP is in use we need to use the full Rx buffer size and not do sharing.

net: Convert some ethtool_sprintf() to ethtool_puts()

2023-12-08T10:56:25Z

This patch converts some basic cases of ethtool_sprintf() to ethtool_puts(). The conversions are used in cases where ethtool_sprintf() was being used with just two arguments: | ethtool_sprintf(&data, buffer[i].name); or when it's used with format string: "%s" | ethtool_sprintf(&data, "%s", buffer[i].name); which both now become: | ethtool_puts(&data, buffer[i].name); Signed-off-by: Justin Stitt Reviewed-by: Wei Fang Reviewed-by: Andrew Lunn Reviewed-by: Louis Peens Signed-off-by: David S.

ionic: remove debug stats

2021-10-02T13:00:21Z

These debug stats are not really useful, their collection is likely detrimental to performance, and they suck up a lot of memory which never gets used if no one ever enables the priv-flag to print them, so just remove these bits. Signed-off-by: Shannon Nelson Signed-off-by: David S. Miller

ionic: fix gathering of debug stats

2021-09-28T12:19:57Z

Don't print stats for which we haven't reserved space as it can cause nasty memory bashing and related bad behaviors. Fixes: aa620993b1e5 ("ionic: pull per-q stats work out of queue loops") Signed-off-by: Shannon Nelson Signed-off-by: David S. Miller

Abstract out the per-queue data collection work into separate functions from the per-queue loops in the stats reporting, similar to what Alex did for the data label strings in commit acebe5b6107c ("ionic: Update driver to use ethtool_sprintf") Signed-off-by: Shannon Nelson Signed-off-by: David S.

ionic: Update driver to use ethtool_sprintf

2021-03-17T18:42:31Z

Update the ionic driver to make use of ethtool_sprintf. In addition add separate functions for Tx/Rx stats strings in order to reduce the total amount of indenting needed in the driver code. Acked-by: Shannon Nelson Signed-off-by: Alexander Duyck Signed-off-by: David S. Miller
