TC0 for the main VSI is\n> also reconfigured as per user provided queue parameters. Queue counts\n> that are not power-of-2 are handled by reconfiguring RSS by reprogramming\n> LUTs using the queue count value.\n> This patch also handles configuring the TX rings for the channels, setting up\n> the RX queue map for channel.\n> \n> Also, the channels so created are removed and all the queue configuration is\n> set to default when the qdisc is detached from the root of the device.\n> \n> v3: Addressed Shannon's feedback removing unwanted code, variables,\n> atomic operations (since setup_tc is protected with rtnl_lock held by stack)\n> and other minor clean up.\n> \n> Signed-off-by: Amritha Nambiar \n> Signed-off-by: Kiran Patil \n> ---\n> drivers/net/ethernet/intel/i40e/i40e.h | 32 +\n> drivers/net/ethernet/intel/i40e/i40e_main.c | 718\n> +++++++++++++++++++++++++++\n> drivers/net/ethernet/intel/i40e/i40e_txrx.h | 2\n> 3 files changed, 743 insertions(+), 9 deletions(-)\n\nTested-by: Andrew Bowers ","headers":{"Return-Path":"","X-Original-To":["incoming@patchwork.ozlabs.org","intel-wired-lan@lists.osuosl.org"],"Delivered-To":["patchwork-incoming@bilbo.ozlabs.org","intel-wired-lan@lists.osuosl.org"],"Authentication-Results":"ozlabs.org;\n\tspf=pass (mailfrom) smtp.mailfrom=osuosl.org\n\t(client-ip=140.211.166.136;
