2018-04-27net: intel: Cleanup the copyright/license headersJeff Kirsher1-19/+1
After many years of having a ~30 line copyright and license header to our source files, we are finally able to reduce that to one line with the advent of the SPDX identifier. Also caught a few files missing the SPDX license identifier, so fixed them up.

2018-03-23intel: add SPDX identifiers to all the Intel driversJeff Kirsher1-0/+1
Add the SPDX identifiers to all the Intel wired LAN driver files, as outlined in Documentation/process/license-rules.rst. Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Tested-by: Aaron Brown <aaron.f.brown@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-10-02fm10k: Use seq_putc() in fm10k_dbg_desc_break()Markus Elfring1-2/+2
Two single characters should be put into a sequence. Thus use the corresponding function "seq_putc". This issue was detected by using the Coccinelle software.

2016-04-20fm10k: consistently use Intel(R) for driver namesJacob Keller1-2/+2
Update every header file and other locations to consistently use Intel(R) instead of just Intel. Also update copyright year of files which we modified.

2015-12-13fm10k: conditionally compile DCB and DebugFS supportJacob Keller1-4/+0
Rather than wrapping fm10k_dcbnl.c and fm10k_debugfs.c support with #ifdef blocks, just conditionally include the .o files in the Makefile. Also, since we're modifying it, update the copyright year on the Makefile.

2015-09-15fm10k: TRIVIAL fix up ordering of __always_unused and styleJacob Keller1-2/+3
Fix some style issues in debugfs code, and correct ordering of void and __always_unused. Technically, the order does not matter, but preferred style is to put the macro between the type and name.

2015-04-14fm10k: fix unused warningsJeff Kirsher1-3/+5
The were several functions which had parameters which were never or sometimes used in functions. To resolve possible compiler warnings, use __always_unused or __maybe_unused kernel macros to resolve.

2014-09-23fm10k: Add support for debugfsAlexander Duyck1-0/+259
This patch adds limited debugfs support for the driver. Most of the functionality needed for dumping registers is already provided via ethtool. The only thing we saw that we really neeed was the ability to dump the descriptor rings so as such this patch will add a fm10k directory containing a listing of directories each one with a unique PCI Bus, Device, and Function number. Each of those BDF directories will have a list of q_vectors, and the q_vectors will contain a file for each of the Rx/Tx rings that are a part of the vector. For example: # ls -RD /sys/kernel/debug/fm10k/ /sys/kernel/debug/fm10k/: 0000:01:00.0 /sys/kernel/debug/fm10k/0000:01:00.0: q_vector.000 q_vector.001 q_vector.002 q_vector.003 /sys/kernel/debug/fm10k/0000:01:00.0/q_vector.000: rx_ring.000 tx_ring.000 /sys/kernel/debug/fm10k/0000:01:00.0/q_vector.001: rx_ring.001 tx_ring.001 /sys/kernel/debug/fm10k/0000:01:00.0/q_vector.002: rx_ring.002 tx_ring.002 /sys/kernel/debug/fm10k/0000:01:00.0/q_vector.003: rx_ring.003 tx_ring.003 # cat /sys/kernel/debug/fm10k/0000:01:00.0/q_vector.000/rx_ring.000 DES DATA RSS STATERR LENGTH VLAN DGLORT SGLORT TIMESTAMP --------------------------------------------------------------------------- 000 0x00000000 0x00000000 0x00000003 0x002a 0x0000 0x0000 0x0000 0x13951807dc4fedf0 001 0x00000000 0x00000000 0x00000003 0x002a 0x0000 0x0000 0x0000 0x1395180906c9f2c8 002 0x3731c000 0x00000000 0x00000000 0x0000 0x0000 0x0000 0x0000 0x0000000000000000 003 0x3731d000 0x00000000 0x00000000 0x0000 0x0000 0x0000 0x0000 0x0000000000000000 004 0xaab3a000 0x00000000 0x00000000 0x0000 0x0000 0x0000 0x0000 0x0000000000000000 ... # cat /sys/kernel/debug/fm10k/0000:01:00.0/q_vector.000/tx_ring.000 DES BUFFER_ADDRESS LENGTH VLAN MSS HDRLEN FLAGS --------------------------------------------------------- 000 0x00000000aa8a1002 0x005a 0x0000 0x0000 0x0000 0xc0 001 0x00000000aa8a2002 0x005a 0x0000 0x0000 0x0000 0xc0 002 0x000000006bc13202 0x004e 0x0000 0x0000 0x0000 0xc0 003 0x000000006bc13c02 0x002a 0x0000 0x0000 0x0000 0xe1 004 0x000000006bc13602 0x0062 0x0000 0x0000 0x0000 0xc0 Signed-off-by: Alexander Duyck <alexander.h.duyck@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
