2016-04-06rtlwifi: btcoexist: Implement antenna selectionLarry Finger
The previous patch added an option to rtl8723be to manually select the antenna for those cases when only a single antenna is present, and the on-board EEPROM is incorrectly programmed. This patch implements the necessary changes in the Bluetooth coexistence driver.

2016-04-06rtlwifi: rtl8723be: Add antenna select module parameterLarry Finger
A number of new laptops have been delivered with only a single antenna. In principle, this is OK; however, a problem arises when the on-board EEPROM is programmed to use the other antenna connection. The option of opening the computer and moving the connector is not always possible as it will void the warranty in some cases. In addition, this solution breaks the Windows driver when the box dual boots Linux and Windows. A fix involving a new module parameter has been developed. This commit adds the new parameter and implements the changes needed for the driver.

2016-04-06i40iw: avoid potential uninitialized variable useArnd Bergmann
gcc finds that the i40iw_make_cm_node() function in the recently added i40iw driver uses an uninitilized variable as an index into an array if CONFIG_IPV6 is disabled and the driver uses IPv6 mode: drivers/infiniband/hw/i40iw/i40iw_cm.c: In function 'i40iw_make_cm_node': drivers/infiniband/hw/i40iw/i40iw_cm.c:2206:52: error: 'arpindex' may be used uninitialized in this function [-Werror=maybe-uninitialized] ether_addr_copy(cm_node->rem_mac, iwdev->arp_table[arpindex].mac_addr); As far as I can tell, this code path can not be used because the ipv4 variable is always set with CONFIG_IPV6 is disabled, but it's better to be sure and prevent the undefined behavior, as well as shut up that warning in a proper way. This adds an 'else' clause for the case we get the warning about, causing the function to return an error in a controlled way. To avoid adding extra mess with combined io()/#ifdef clauses, I'm also converting the existing #ifdef into a more readable if(IS_ENABLED()) check.

2016-04-05net: bcmgenet: cleanup for dmadesc_set()Petri Gynther
dmadesc_set() is used for setting the Tx buffer DMA address, length, and status bits on a Tx ring descriptor when a frame is being Tx'ed. Always set the Tx buffer DMA address first, before updating the length and status bits, i.e. giving the Tx descriptor to the hardware. The reason this is a cleanup rather than a fix is that the hardware won't transmit anything from a Tx ring until the TDMA producer index has been incremented. As long as the dmadesc_set() writes complete before the TDMA producer index write, life is good.

2016-04-05e1000: Double Tx descriptors needed check for 82544Alexander Duyck
The 82544 has code that adds one additional descriptor per data buffer. However we weren't taking that into account when determining the descriptors needed for the next transmit at the end of the xmit_frame path. This change takes that into account by doubling the number of descriptors needed for the 82544 so that we can avoid a potential issue where we could hang the Tx ring by loading frames with xmit_more enabled and then stopping the ring without writing the tail. In addition it adds a few more descriptors to account for some additional workarounds that have been added over time.

2016-04-05e1000: Do not overestimate descriptor counts in Tx pre-checkAlexander Duyck
The current code path is capable of grossly overestimating the number of descriptors needed to transmit a new frame. This specifically occurs if the skb contains a number of 4K pages. The issue is that the logic for determining the descriptors needed is ((S) >> (X)) + 1. When X is 12 it means that we were indicating that we required 2 descriptors for each 4K page when we only needed one. This change corrects this by instead adding (1 << (X)) - 1 to the S value instead of adding 1 after the fact. This way we get an accurate descriptor needed count as we are essentially doing a DIV_ROUNDUP().

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2016-04-05 This series contains updates to i40e and i40evf only. Stefan converts dev_close() to ndo_stop() for ethtool offline self test, since dev_close() causes IFF_UP to be cleared which will remove the interface routes and addresses. Alex bumps up the size of the transmit data buffer to 12K rather than 8K, which provides a gain in throughput and a reduction in overhead for putting together the frame. Fixed an issue in the polling routines where we were using bitwise operators to avoid the side effects of the logical operators. Then added support for bulk transmit clean for skbs. Jesse fixed a sparse issue in the type casting in the transmit code and fixed i40e_aq_set_phy_debug() to use i40e_status as a return code. Catherine cleans up duplicated code. Shannon fixed the cleaning up of the interrupt handling to clean up the IRQs only if we actually got them set up. Also fixed up the error scenarios where we were trying to remove a non-existent timer or worktask, which causes the kernel heartburn. Mitch changes the notification of resets to the reset interrupt handler, instead of the actual reset initiation code. This allows the VFs to get properly notified for all resets, including resets initiated by different PFs on the same physical device. Also moved the clearing of VFLR bit after reset processing, instead of before which could lead to double resets on VF init. Fixed code comment to match the actual function name. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
