2023-12-13net: ethtool: pass a pointer to parameters to get/set_rxfh ethtool opsAhmed Zaki1-19/+19
The get/set_rxfh ethtool ops currently takes the rxfh (RSS) parameters as direct function arguments. This will force us to change the API (and all drivers' functions) every time some new parameters are added. This is part 1/2 of the fix, as suggested in [1]: - First simplify the code by always providing a pointer to all params (indir, key and func); the fact that some of them may be NULL seems like a weird historic thing or a premature optimization. It will simplify the drivers if all pointers are always present. - Then make the functions take a dev pointer, and a pointer to a single struct wrapping all arguments. The set_* should also take an extack.

This patch converts some basic cases of ethtool_sprintf() to ethtool_puts().

Move the nfp_net_get_port_mac_by_hwinfo() check to ahead in the get/set_eeprom() functions to in order to check for a VF netdev, which this function does not support. It is debatable if this is a fix or an enhancement, and we have chosen to go for the latter. It does address a problem introduced by commit 74b4f1739d4e ("nfp: flower: change get/set_eeprom logic and enable for flower reps"). However, the ethtool->len == 0 check avoids the problem manifesting as a run-time bug (NULL pointer dereference of app).

2023-01-24nfp: flower: change get/set_eeprom logic and enable for flower repsJames Hershaw1-4/+7
The changes in this patch are as follows: - Alter the logic of get/set_eeprom functions to use the helper function nfp_app_from_netdev() which handles differentiating between an nfp_net and a nfp_repr. This allows us to get an agnostic backpointer to the pdev. - Enable the various eeprom commands by adding the 'get_eeprom_len', 'get_eeprom', 'set_eeprom' callbacks to the nfp_port_ethtool_ops struct. This allows the eeprom commands to work on representor interfaces, similar to a previous patch which added it to the vnics. Currently these are being used to configure persistent MAC addresses for the physical ports on the nfp.

For SFF-8636 and SFF-8436 specifications, the driver exposes 256 bytes of EEPROM data for ethtool's get_module_eeprom() callback, resulting in "netlink error: Invalid argument" when an EEPROM read with an offset larger than 256 bytes is attempted. Changing the length enumerators to the _MAX_LEN variants exposes all 640 bytes of the EEPROM allowing upper pages 1, 2 and 3 to be read.

If the reader is in preemptible context and the writer side (u64_stats_update_begin*()) runs in an interrupt context (IRQ or softirq) then the writer can update the stats during the read operation.

2019-12-19nfp: tls: implement the stream sync RX resyncJakub Kicinski1-1/+7
The simple RX resync strategy controlled by the kernel does not guarantee as good results as if the device helps by detecting the potential record boundaries and keeping track of them. We've called this strategy stream scan in the tls-offload doc. Implement this strategy for the NFP. The device sends a request for record boundary confirmation, which is then recorded in per-TLS socket state and responded to once record is reached. Because the device keeps track of records passing after the request was sent the response is not as latency sensitive as when kernel just tries to tell the device the information about the next record.
