net: intel: Remove in_interrupt() warnings

2020-09-29T21:02:54Z

in_interrupt() is ill defined and does not provide what the name suggests. The usage especially in driver code is deprecated and a tree wide effort to clean up and consolidate the (ab)usage of in_interrupt() and related checks is happening. In this case the checks cover only parts of the contexts in which these functions cannot be called. They fail to detect preemption or interrupt disabled invocations. As the functions which are invoked from the various places contain already a broad variety of checks (always enabled or debug option dependent) cover all invalid conditions already, there is no point in having inconsistent warnings in those drivers. Just remove them. Signed-off-by: Sebastian Andrzej Siewior Signed-off-by: Thomas Gleixner Reviewed-by: Alexander Duyck Signed-off-by: David S. Miller

igb: add XDP support

2020-09-28T21:42:45Z

Add XDP support to the IGB driver. The implementation follows the IXGBE XDP implementation closely and I used the following patches as basis: 1. commit 924708081629 ("ixgbe: add XDP support for pass and drop actions") 2. commit 33fdc82f0883 ("ixgbe: add support for XDP_TX action") 3. commit ed93a3987128 ("ixgbe: tweak page counting for XDP_REDIRECT") Due to the hardware constraints of the devices using the IGB driver we must share the TX queues with XDP which means locking the TX queue for XDP. I ran tests on an older device to get better numbers. Test machine: Intel(R) Atom(TM) CPU C2338 @ 1.74GHz (2 Cores) 2x Intel I211 Routing Original Driver Network Stack: 382 Kpps Routing XDP Redirect (xdp_fwd_kern): 1.48 Mpps XDP Drop: 1.48 Mpps Using XDP we can achieve line rate forwarding even on an older Intel Atom CPU.

intel-ethernet: clean up W=1 warnings in kdoc

2020-09-25T23:28:59Z

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.

We got slightly different patches removing a double word in a comment in net/ipv4/raw.c - picked the version from net. Simple conflict in drivers/net/ethernet/ibm/ibmvnic.c. Use cached values instead of VNIC login response buffer (following what commit 507ebe6444a4 ("ibmvnic: Fix use-after-free of VNIC login response buffer") did). Signed-off-by: Jakub Kicinski

net: Take common prefetch code structure into a function

Many device drivers use the same prefetch code structure to deal with small L1 cacheline size. Take this code into a function and call it from the drivers. Suggested-by: Jakub Kicinski Signed-off-by: Tariq Toukan Reviewed-by: Saeed Mahameed Signed-off-by: David S. Miller
