When user-space uses a valid ISO-3166-1 country code for its regulatory domain selection, the driver will try to configure the firmware to use the same. Reviewed-by:

When there is no room in the ring for rxbufpost an error is logged, however this happens quite frequently and can be considered normal and is certainly recoverable. This patch changes the erorr into a normal msgbuf log. Reviewed-by:

When a device is configured for AP mode and it is configured for WEP then the keys are plumbed first, followed by AP configuration. During configuration a down command is given to the firmware which will clear the configured keys. This patch reprograms the WEP keys after AP has been brought up. Reviewed-by:

The physical addresses being used by pcie and msgbuf were using a cast to long, which incorrectly caused it to limit the address to 32bit. Now explicit u64 is used where needed. Reviewed-by:

Richard Cochran says: ==================== Fixing the "Time Counter fixes and improvements" For this series I had only tested the build with ARCH=x86 and arm, but others like sparc64, microblaze, powerpc, and s390 will fail because they somehow don't indirectly include clocksource.h for the drivers in question. This series fixes the build issues reported by: kbuild test robot <fengguang.wu@intel.com> ==================== Signed-off-by:David S. Miller <davem@davemloft.net>

Not needed, only four cases: - kfree_skb (or one of its aliases). Don't need to zero, memory will be freed. - kfree_skb_partial and head was stolen: memory will be freed. - skb_morph: The skb header fields (including tc ones) will be copied over from the 'to-be-morphed' skb right after skb_release_head_state returns. - skb_segment: Same as before, all the skb header fields are copied over from the original skb right away.

This driver is based on stmmac driver. changes since v2: - use tab instead of space for macros - use HIWORD_UPDATE macro for GMAC_CLK_RX_DL_CFG and GMAC_CLK_TX_DL_CFG - remove drive-strength setting in the driver and set it in the pinctrl settings - use dev_err instead of pr_err - remove clock names's macros, just use the real name of the clock - use devm_clk_get() instead of clk_get() - remove clk_set_parent(bsp_priv->clk_mac, bsp_priv->clk_mac_pll) - remove gpio setting for LDO, just use regulator API - remove phy reset using gpio in the glue layer, it has been handled in the stmmac driver - remove handling phy interrupt (mii interrupt) changes since v1: - use BIT() to set register - combine two remap_write() operations into one for the same register - use macros for register value setting - remove grf fail check in rk_gmac_setup() and save all the check in set_rgmii_speed() - remove .tx_coe=1 in rk_gmac_data Signed-off-by:

Alexander Duyck says: ==================== fib_trie: Reduce time spent in fib_table_lookup by 35 to 75% These patches are meant to address several performance issues I have seen in the fib_trie implementation, and fib_table_lookup specifically. With these changes in place I have seen a reduction of up to 35 to 75% for the total time spent in fib_table_lookup depending on the type of search being performed. On a VM running in my Corei7-4930K system with a trie of maximum depth of 7 this resulted in a reduction of over 370ns per packet in the total time to process packets received from an ixgbe interface and route them to a dummy interface. This represents a failed lookup in the local trie followed by a successful search in the main trie. Baseline Refactor ixgbe->dummy routing 1.20Mpps 2.21Mpps ------------------------------------------------------------ processing time per packet 835ns 453ns fib_table_lookup 50.1% 418ns 25.0% 113ns check_leaf.isra.9 7.9% 66ns -- -- ixgbe_clean_rx_irq 5.3% 44ns 9.8% 44ns ip_route_input_noref 2.9% 25ns 4.6% 21ns pvclock_clocksource_read 2.6% 21ns 4.6% 21ns ip_rcv 2.6% 22ns 4.0% 18ns In the simple case of receiving a frame and dropping it before it can reach the socket layer I saw a reduction of 40ns per packet. This represents a trip through the local trie with the correct leaf found with no need for any backtracing. Baseline Refactor ixgbe->local receive 2.65Mpps 2.96Mpps ------------------------------------------------------------ processing time per packet 377ns 337ns fib_table_lookup 25.1% 95ns 25.8% 87ns ixgbe_clean_rx_irq 8.7% 33ns 9.0% 30ns check_leaf.isra.9 7.2% 27ns -- -- ip_rcv 5.7% 21ns 6.5% 22ns These changes have resulted in several functions being inlined such as check_leaf and fib_find_node, but due to the code simplification the overall size of the code has been reduced. text data bss dec hex filename 16932 376 16 17324 43ac net/ipv4/fib_trie.o - before 15259 376 8 15643 3d1b net/ipv4/fib_trie.o - after Changes since RFC: Replaced this_cpu_ptr with correct call to this_cpu_inc in patch 1 Changed test for leaf_info mismatch to (key ^ n->key) & li->mask_plen in patch 10 ==================== Signed-off-by: -

This change adds a tracking value for the maximum suffix length of all prefixes stored in any given tnode. With this value we can determine if we need to backtrace or not based on if the suffix is greater than the pos value. By doing this we can reduce the CPU overhead for lookups in the local table as many of the prefixes there are 32b long and have a suffix length of 0 meaning we can immediately backtrace to the root node without needing to test any of the nodes between it and where we ended up.
