net: Convert GRO SKB handling to list_head.

2018-06-26T02:33:04+00:00

Manage pending per-NAPI GRO packets via list_head.

Return an SKB pointer from the GRO receive handlers.  When GRO receive
handlers return non-NULL, it means that this SKB needs to be completed
at this time and removed from the NAPI queue.

Several operations are greatly simplified by this transformation,
especially timing out the oldest SKB in the list when gro_count
exceeds MAX_GRO_SKBS, and napi_gro_flush() which walks the queue
in reverse order.

net: Extra '_get' in declaration of arch_get_platform_mac_address

2018-02-08T20:13:30+00:00

In commit c7f5d105495a ("net: Add eth_platform_get_mac_address() helper."),
two declarations were added:

  int eth_platform_get_mac_address(struct device *dev, u8 *mac_addr);
  unsigned char *arch_get_platform_get_mac_address(void);

An extra '_get' was introduced in arch_get_platform_get_mac_address, remove
it. Fix compile warning using W=1:

net: Define eth_stp_addr in linux/etherdevice.h

2017-11-03T05:17:39+00:00

The lan9303 driver defines eth_stp_addr as a synonym to
eth_reserved_addr_base to get the STP ethernet address 01:80:c2:00:00:00.

eth_reserved_addr_base is also used to define the start of Bridge Reserved
ethernet address range, which happen to be the STP address.

br_dev_setup refer to eth_reserved_addr_base as a definition of STP
address.

Clean up by:
 - Move the eth_stp_addr definition to linux/etherdevice.h
 - Use eth_stp_addr instead of eth_reserved_addr_base in br_dev_setup.

etherdevice: remove unused eth_addr_greater

2017-03-13T06:54:07+00:00

eth_addr_greater() was introduced for the mv88e6xxx driver, but is not
used anymore. There is no other user, thus remove this function.

net: add devm version of alloc_etherdev_mqs function

2017-01-30T00:24:12+00:00

This patch adds devm_alloc_etherdev_mqs function and devm_alloc_etherdev
macro. These can be used for simpler netdev allocation without having to
care about calling free_netdev.

Thanks to this change drivers, their error paths and removal paths may
get simpler by a bit.

dsa: mv88e6xxx: Optimise atu_get

2017-01-04T21:34:34+00:00

Lookup in the ATU can be performed starting from a given MAC
address. This is faster than starting with the first possible MAC
address and iterating all entries.

Entries are returned in numeric order. So if the MAC address returned
is bigger than what we are searching for, we know it is not in the
ATU.

Using the benchmark provided by Volodymyr Bendiuga
,

https://www.spinics.net/lists/netdev/msg411550.html

on an Marvell Armada 370 RD, the test to add a number of static fdb
entries went from 1.616531 seconds to 0.312052 seconds.

net: Add eth_platform_get_mac_address() helper.

2016-01-06T21:31:56+00:00

A repeating pattern in drivers has become to use OF node information
and, if not found, platform specific host information to extract the
ethernet address for a given device.

Currently this is done with a call to of_get_mac_address() and then
some ifdef'd stuff for SPARC.

Consolidate this into a portable routine, and provide the
arch_get_platform_mac_address() weak function hook for all
architectures to implement if they want.

net: fix endian check warning in etherdevice.h

Sparse builds have been warning for a really long time now

etherdev: Fix sparse error, make test usable by other functions

2015-05-05T23:24:42+00:00

This change does two things.  First it fixes a sparse error for the fact
that the __be16 degrades to an integer.  Since that is actually what I am
kind of doing I am simply working around that by forcing both sides of the
comparison to u16.

Also I realized on some compilers I was generating another instruction for
big endian systems such as PowerPC since it was masking the value before
doing the comparison.  So to resolve that I have simply pulled the mask out
and wrapped it in an #ifndef __BIG_ENDIAN.

Lastly I pulled this all out into its own function.  I notices there are
similar checks in a number of other places so this function can be reused
there to help reduce overhead in these paths as well.
