2022-12-01net: dpaa2: replace dpaa2_mac_is_type_fixed() with dpaa2_mac_is_type_phy()Vladimir Oltean
dpaa2_mac_is_type_fixed() is a header with no implementation and no callers, which is referenced from the documentation though. It can be deleted. On the other hand, it would be useful to reuse the code between dpaa2_eth_is_type_phy() and dpaa2_switch_port_is_type_phy(). That common code should be called dpaa2_mac_is_type_phy(), so let's create that. The removal and the addition are merged into the same patch because, in fact, is_type_phy() is the logical opposite of is_type_fixed().

dpaa2_eth_setup_dpni() is called from the probe path and dpaa2_eth_set_link_ksettings() is propagated to user space. include/linux/errno.h says that ENOTSUPP is "Defined for the NFSv3 protocol".

If vcap_dup_rule() fails that leads to an error pointer dereference side the call to vcap_free_rule(). Also it only returns an error if the very last call to vcap_read_rule() fails and it returns success for other errors.

2022-11-30ice: use same function to snapshot both NVM and Shadow RAMJacob Keller
The ice driver supports a region for both the flat NVM contents as well as the Shadow RAM which is a layer built on top of the flash during device initialization. These regions use an almost identical read function, except that the NVM needs to set the direct flag when reading, while Shadow RAM needs to read without the direct flag set. They each call ice_read_flat_nvm with the only difference being whether to set the direct flash flag. The NVM region read function also was fixed to read the NVM in blocks to avoid a situation where the firmware reclaims the lock due to taking too long. Note that the region snapshot function takes the ops pointer so the function can easily determine which region to read. Make use of this and re-use the NVM snapshot function for both the NVM and Shadow RAM regions. This makes Shadow RAM benefit from the same block approach as the NVM region. It also reduces code in the ice driver. Signed-off-by: Jacob Keller <jacob.e.keller@intel.com> Acked-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2022-11-30net: microchip: vcap: Change how the rule id is generatedHoratiu Vultur
Currently whenever a new rule id is generated, it picks up the next number bigger than previous id. So it would always be 1, 2, 3, etc. When the rule with id 1 will be deleted and a new rule will be added, it will have the id 4 and not id 1. In theory this can be a problem if at some point a rule will be added and removed ~0 times. Then no more rules can be added because there are no more ids. Change this such that when a new rule is added, search for an empty rule id starting with value of 1 as value 0 is reserved.

2022-11-30octeontx2-af: Fix the size of memory allocated for the 'id_bmap' bitmapChristophe JAILLET
This allocation is really spurious. The size of the bitmap is 'tot_ids' and it is used as such in the driver. So we could expect something like: table->id_bmap = devm_kcalloc(rvu->dev, BITS_TO_LONGS(table->tot_ids), sizeof(long), GFP_KERNEL); However, when the bitmap is allocated, we allocate: BITS_TO_LONGS(table->tot_ids) * table->tot_ids ~= table->tot_ids / 32 * table->tot_ids ~= table->tot_ids^2 / 32 It is proportional to the square of 'table->tot_ids' which seems to potentially be big. Allocate the expected amount of memory, and switch to the bitmap API to have it more straightforward.

2022-11-30e1000e: Fix TX dispatch conditionAkihiko Odaki
e1000_xmit_frame is expected to stop the queue and dispatch frames to hardware if there is not sufficient space for the next frame in the buffer, but sometimes it failed to do so because the estimated maximum size of frame was wrong. As the consequence, the later invocation of e1000_xmit_frame failed with NETDEV_TX_BUSY, and the frame in the buffer remained forever, resulting in a watchdog failure. This change fixes the estimated size by making it match with the condition for NETDEV_TX_BUSY. Apparently, the old estimation failed to account for the following lines which determines the space requirement for not causing NETDEV_TX_BUSY: ``` /* reserve a descriptor for the offload context */ if ((mss) || (skb->ip_summed == CHECKSUM_PARTIAL)) count++; count++; count += DIV_ROUND_UP(len, adapter->tx_fifo_limit); ``` This issue was found when running http-stress02 test included in Linux Test Project 20220930 on QEMU with the following commandline: ``` qemu-system-x86_64 -M q35,accel=kvm -m 8G -smp 8 -drive if=virtio,format=raw,file=root.img,file.locking=on -device e1000e,netdev=netdev -netdev tap,script=ifup,downscript=no,id=netdev ``` Fixes: bc7f75fa9788 ("[E1000E]: New pci-express e1000 driver (currently for ICH9 devices only)") Signed-off-by: Akihiko Odaki <akihiko.odaki@daynix.com> Tested-by: Gurucharan G <gurucharanx.g@intel.com> (A Contingent worker at Intel) Tested-by: Naama Meir <naamax.meir@linux.intel.com> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com>

Per the device spec, MTTs/KLMs list in a UMR WQE must be aligned to 64B. Per our SW design, the MTT/KLMs list would need alignment only if it's too small, for example on PPC when PAGE_SIZE is 64KB, and only 4 pages are needed to cover a MPWQE of size 256KB. Padding, if needed, is taken into account when calculating the UMR WQE fields (ds_cnt and xlt_octowords), however no entries are provided, instead garbage is passed. No real harm though, as these parts act as gaps between the RX MPWQEs and not used by any of them. Hence, in practice, device does not try to write any incoming packet to them. Still, prefer providing clean padding marking the end of the list, and do not map garbage into the RQ memory region.

2022-11-29Revert "net/mlx5e: MACsec, remove replay window size limitation in offload path"Saeed Mahameed
This reverts commit c0071be0e16c461680d87b763ba1ee5e46548fde. The cited commit removed the validity checks which initialized the window_sz and never removed the use of the now uninitialized variable, so now we are left with wrong value in the window size and the following clang warning: [-Wuninitialized] drivers/net/ethernet/mellanox/mlx5/core/en_accel/macsec.c:232:45: warning: variable 'window_sz' is uninitialized when used here MLX5_SET(macsec_aso, aso_ctx, window_size, window_sz); Revet at this time to address the clang issue due to lack of time to test the proper solution.

2022-11-29nfp: ethtool: support reporting link modesYu Xiao
Add support for reporting link modes, including `Supported link modes` and `Advertised link modes`, via ethtool $DEV. A new command `SPCODE_READ_MEDIA` is added to read info from management firmware. Also, the mapping table `nfp_eth_media_table` associates the link modes between NFP and kernel. Both of them help to support this ability.

2022-11-29net: microchip: vcap: Merge the vcap_ag_api_kunit.h into vcap_ag_api.hHoratiu Vultur
Currently there are 2 files that contain the keyfields, keys, actionfields and actions. First file is used by the kunit while the second one is used by VCAP api. The header file that is used by kunit is just a super set of the of the header file used by VCAP api. Therefore not to have duplicate information in different files which is also harder to maintain, create a single file that is used both by API and by kunit.
