i40e: use int for i40e_status

2023-05-11T14:11:36Z

commit 5180ff1364bc26c031b54a68a80aa90ce0028b70 upstream. To prepare for removal of i40e_status, change the variables from i40e_status to int. This eases the transition when values are changed to return standard int error codes over enum i40e_status. As such changes often also change variable orders, a cleanup is also applied here to make variables conform to RCT and some lines are also reformatted where applicable.

i40e: Remove string printing for i40e_status

2023-05-11T14:11:36Z

commit 5d968af27a166e055bdd5f832f095d809eadb992 upstream. Remove the i40e_stat_str() function which prints the string representation of the i40e_status error code. With upcoming changes moving away from i40e_status, there will be no need for this function Signed-off-by: Jan Sokolowski Tested-by: Gurucharan G (A Contingent worker at Intel) Signed-off-by: Tony Nguyen Signed-off-by: Greg Kroah-Hartman

i40e: Remove unused i40e status codes

2023-05-11T14:11:36Z

commit 9d135352bb5d885a7b21417103423301a40c1b8b upstream. In an effort to remove i40e status codes and replace them with standard kernel errornums, unused values of i40e_status_code were removed.

i40e: allow toggling loopback mode via ndo_set_features callback

2022-12-12T23:24:47Z

Add support for NETIF_F_LOOPBACK. This feature can be set via: $ ethtool -K eth0 loopback This sets the MAC Tx->Rx loopback. This feature is used for the xsk selftests, and might have other uses too.

i40e: Add new version of i40e_aq_add_macvlan function

2022-02-03T21:13:51Z

ASQ send command functions are returning only i40e status codes yet some calling functions also need Admin Queue status that is stored in hw->aq.asq_last_status. Since hw object is stored on a heap it introduces a possibility for a race condition in access to hw if calling function is not fast enough to read hw->aq.asq_last_status before next send ASQ command is executed. Add new _v2 version of i40e_aq_add_macvlan that is using new _v2 versions of ASQ send command functions and returns the Admin Queue status on the stack.

i40e: Add sending commands in atomic context

2022-02-03T21:13:50Z

Change functions: - i40e_aq_add_macvlan - i40e_aq_remove_macvlan - i40e_aq_delete_element - i40e_aq_add_vsi - i40e_aq_update_vsi_params to explicitly use i40e_asq_send_command_atomic(..., true) instead of i40e_asq_send_command, as they use mutexes and do some work in an atomic context. Without this change setting vlan via netdev will fail with call trace cased by bug "BUG: scheduling while atomic".

i40e: remove variables set but not used

2022-01-07T17:04:21Z

The code that uses variables pe_cntx_size and pe_filt_size has been removed, so they should be removed as well. Eliminate the following clang warnings: drivers/net/ethernet/intel/i40e/i40e_common.c:4139:20: warning: variable 'pe_filt_size' set but not used. drivers/net/ethernet/intel/i40e/i40e_common.c:4139:6: warning: variable 'pe_cntx_size' set but not used.
