This is a simple cleanup addressing two coding style issues found by checkpatch.pl in an earlier patch. It's submitted as a separate patch to keep the original patch as it was generated by spatch. Signed-off-by:

After the previous commit, both ipset_nest_start() and ipset_nest_end() are just aliases for nla_nest_start() and nla_nest_end() so that there is no need to keep them. Signed-off-by:

Even if the NLA_F_NESTED flag was introduced more than 11 years ago, most netlink based interfaces (including recently added ones) are still not setting it in kernel generated messages. Without the flag, message parsers not aware of attribute semantics (e.g. wireshark dissector or libmnl's mnl_nlmsg_fprintf()) cannot recognize nested attributes and won't display the structure of their contents. Unfortunately we cannot just add the flag everywhere as there may be userspace applications which check nlattr::nla_type directly rather than through a helper masking out the flags. Therefore the patch renames nla_nest_start() to nla_nest_start_noflag() and introduces nla_nest_start() as a wrapper adding NLA_F_NESTED. The calls which add NLA_F_NESTED manually are rewritten to use nla_nest_start(). Except for changes in include/net/netlink.h, the patch was generated using this semantic patch: @@ expression E1, E2; @@ -nla_nest_start(E1, E2) +nla_nest_start_noflag(E1, E2) @@ expression E1, E2; @@ -nla_nest_start_noflag(E1, E2 | NLA_F_NESTED) +nla_nest_start(E1, E2) Signed-off-by:

There seems to be no reason for tls_ops to be defined in netdevice.h which is included in a lot of places. Don't wrap the struct/enum declaration in ifdefs, it trickles down unnecessary ifdefs into driver code. Signed-off-by:

tls_device_sk_destruct being set on a socket used to indicate that socket is a kTLS device one. That is no longer true - now we use sk_validate_xmit_skb pointer for that purpose. Remove the export. tls_device_attach() needs to be moved. While at it, remove the dead declaration of tls_sk_destruct(). Signed-off-by:

Currently when CONFIG_TLS_DEVICE is set each time kTLS connection is opened and the offload is not successful (either because the underlying device doesn't support it or e.g. it's tables are full) a rate limited error will be printed to the logs. There is nothing wrong with failing TLS offload. SW path will process the packets just fine, drop the noisy messages. Signed-off-by:

It's meaningless to trigger reset when failed to send command to IMP, because the failure is usually caused by no authority, illegal command and so on. When that happened, we just need to return the status code for further debugging. Signed-off-by:

The bdinfo handled in hns3_handle_bdinfo is only valid on the last BD of the current packet, currently the bd info may be handled based on the first BD if the packet has more than two BDs, which may cause rx error. This patch fixes it by using the last BD of the current packet in hns3_handle_bdinfo. Also, hns3_set_rx_skb_rss_type has used RSS hash value from the last BD of the current packet, so remove the same last BD calculation in hns3_set_rx_skb_rss_type and call it from hns3_handle_bdinfo.

hns3_desc_unused() returns how many BD have been cleaned, but new buffer has not been attached to them. The register of HNS3_RING_RX_RING_FBDNUM_REG returns how many BD need allocating new buffer to or need to cleaned. So the remaining BD need to be clean is HNS3_RING_RX_RING_FBDNUM_REG - hns3_desc_unused(). Also, new buffer can not attach to the pending BD when the last BD is not handled, because memcpy has not been done on the first pending BD. This patch fixes by subtracting the pending BD num from unused_count after 'HNS3_RING_RX_RING_FBDNUM_REG - unused_count' is used to calculate the BD bum need to be clean.

hns3_clean_tx_ring calls hns3_nic_reclaim_one_desc to clean buffers and set ring->next_to_clean, then hns3_nic_net_xmit reuses the cleaned buffers. But there are no memory barriers when buffers gets recycled, so the recycled buffers can be corrupted. This patch uses smp_store_release to update ring->next_to_clean and smp_load_acquire to read ring->next_to_clean to properly hand off buffers from hns3_clean_tx_ring to hns3_nic_net_xmit.

PHY's behave differently when being reset. Some reset registers to defaults, some don't. Some trigger an autoneg restart, some don't. So let's also set the autoneg restart bit when resetting. Then PHY behavior should be more consistent. Clearing BMCR_ISOLATE serves the same purpose and is borrowed from genphy_restart_aneg. BMCR holds the speed / duplex settings in fixed mode. Therefore we may have an issue if a soft reset resets BMCR to its default. So better call genphy_setup_forced() afterwards in fixed mode. We've seen no related complaint in the last >10 yrs, so let's treat it as an improvement. Signed-off-by:

When building the L3 HW header for non-IP packets, trust the cast type that was passed as parameter. qeth_l3_get_cast_type() has most likely also used h_dest to determine the cast type, so we get the same result, and can remove that duplicated code. In the unlikely case that we would get a _different_ cast type, then that's based off a route lookup and should be considered authoritative. Signed-off-by:

On the first initialization of a queue, its Output Buffers are in a clean state with no attached resources. On every subsequent initialization, qeth_l?_stop_card() has previously put them in a clean state via qeth_drain_output_queues(). So the call to qeth_clear_output_buffer() is redundant and can be removed. While at it, move the initialization of the queue's card pointer into the queue allocation. It never changes afterwards.
