2025-06-25wifi: iwlwifi: mld: don't exit EMLSR when we shouldn'tMiri Korenblit
There is a requirement to exit EMLSR if there wasn't enough throughput in the secondary link. This is checked in check_tpt_wk, which runs every 5 seconds in a high throughput scenario (when the throughput blocker isn't set) It can happen that this worker is running immediately after we entered EMLSR, and in that case the secondary link didn't have a chance to have throughput. In that case we will exit EMLSR for no good reason. Fix this by tracking the time we entered EMLSR, and in the worker make sure that 5 seconds passed from when we entered EMLSR. If not, don't check the secondary link throughput.

This turned out to be a result of missed XDP flush on redirect lists. By digging in the actual source code, we found that commit 7f0a168b0441 ("bnxt_en: Add completion ring pointer in TX and RX ring structures") incorrectly overwrites the event mask for XDP_REDIRECT in bnxt_rx_xdp. We can stably reproduce this crash by returning XDP_TX and XDP_REDIRECT randomly for incoming packets in a naive XDP program. Properly propagate the XDP_REDIRECT events back fixes the crash.

2025-06-24net: xsk: dpaa2: avoid repeatedly updating the global consumerJason Xing
This patch avoids another update of the consumer at the end of dpaa2_xsk_tx(). In the zero copy xmit path, two versions (batched and non-batched) regarding how the consumer of tx ring changes are implemented in xsk_tx_peek_release_desc_batch() that eventually updates the local consumer to the global consumer in either of the following call trace: 1) batched mode: xsk_tx_peek_release_desc_batch() __xskq_cons_release() 2) non-batched mode: xsk_tx_peek_release_desc_batch() xsk_tx_peek_release_fallback() xsk_tx_release() As we can see, dpaa2_xsk_tx() doesn't need to call extra release function to handle the sync of consumer itself.
