2020-09-25intel-ethernet: clean up W=1 warnings in kdocJesse Brandeburg1-2/+2
This takes care of all of the trivial W=1 fixes in the Intel Ethernet drivers, which allows developers and maintainers to build more of the networking tree with more complete warning checks. There are three classes of kdoc warnings fixed: - cannot understand function prototype: 'x' - Excess function parameter 'x' description in 'y' - Function parameter or member 'x' not described in 'y' All of the changes were trivial comment updates on function headers. Inspired by Lee Jones' series of wireless work to do the same. Compile tested only, and passes simple test of $ git ls-files *.[ch] | egrep drivers/net/ethernet/intel | \ xargs scripts/kernel-doc -none Signed-off-by: Jesse Brandeburg <[email protected]> Tested-by: Aaron Brown <[email protected]> Signed-off-by: David S.

Trusted VF with unicast promiscuous mode set, could listen to TX traffic of other VFs. Set unicast promiscuous mode to RX traffic, if VSI has port VLAN configured.

2019-09-09i40e: Implement debug macro hw_dbg using dev_dbgMauro S. M. Rodrigues1-0/+1
There are several uses of hw_dbg in the code, producing no output. This patch implements it using dev_debug. Initially the intention was to implement it using netdev_dbg, analogously to what is done in ixgbe for instance. That approach was avoided due to some early usages of hw_dbg, like i40e_pf_reset, before the VSI structure initialization causing NULL pointer dereference during the driver probe if the debug messages were turned on as soon as the module is probed. v2: - Use dev_dbg instead of pr_debug, and take advantage of dev_name instead of crafting pretty much the same device name locally as suggested by Jakub Kicinski.

2019-08-22i40e: allow reset in recovery modePiotr Kwapulinski1-1/+1
Driver waits after issuing a reset. When a reset takes too long a driver gives up. Implemented by invoking PF reset in a loop. After defined number of unsuccessful PF reset trials it returns error. Without this patch PF reset fails when NIC is in recovery mode. So make i40e_set_mac_type() public. i40e driver requires i40e_set_mac_type() to be public. It is required for recovery mode handling. Without this patch recovery mode could not be detected in i40e_probe().

2019-08-22i40e: reduce stack usage in i40e_set_fcArnd Bergmann1-40/+51
The functions i40e_aq_get_phy_abilities_resp() and i40e_set_fc() both have giant structure on the stack, which makes each one use stack frames larger than 500 bytes. As clang decides one function into the other, we get a warning for exceeding the frame size limit on 32-bit architectures: drivers/net/ethernet/intel/i40e/i40e_common.c:1654:23: error: stack frame size of 1116 bytes in function 'i40e_set_fc' [-Werror,-Wframe-larger-than=] When building with gcc, the inlining does not happen, but i40e_set_fc() calls i40e_aq_get_phy_abilities_resp() anyway, so they add up on the kernel stack just as much. The parts that actually use large stacks don't overlap, so make sure each one is a separate function, and mark them as noinline_for_stack to prevent the compilers from combining them again.
