This patch fixes a bug where the i40e Tx queue will hang if this skb is passed to the driver. With mixed size fragments while using TSO there was a corner case where we needed to linearize but we were not. This was seen with iSCSI traffic and could be reproduced with a frag list that looks like this: num_frags = 17, gso_segs = 17, hdr_len = 66, skb_shinfo(skb)->gso_size = 1448 size = 3002, j = 1, frag_size = 2936, num_frags = 17 size = 4268, j = 1, frag_size = 4096, num_frags = 16 size = 5534, j = 1, frag_size = 4096, num_frags = 15 size = 5352, j = 1, frag_size = 4096, num_frags = 14 size = 5170, j = 1, frag_size = 4096, num_frags = 13 size = 3468, j = 1, frag_size = 2576, num_frags = 12 size = 750, j = 1, frag_size = 112, num_frags = 11 size = 862, j = 2, frag_size = 112, num_frags = 10 size = 974, j = 3, frag_size = 112, num_frags = 9 size = 1126, j = 4, frag_size = 152, num_frags = 8 size = 1330, j = 5, frag_size = 204, num_frags = 7 size = 1534, j = 6, frag_size = 204, num_frags = 6 size = 356, j = 1, frag_size = 204, num_frags = 5 size = 560, j = 2, frag_size = 204, num_frags = 4 size = 764, j = 3, frag_size = 204, num_frags = 3 size = 968, j = 4, frag_size = 204, num_frags = 2 size = 1140, j = 5, frag_size = 172, num_frags = 1 result: linearize = 0, j = 6 Change-ID: I79bb1aeab0af255fe2ce28e93672a85d85bf47e8 Signed-off-by: Anjali Singhai Jain <anjali.singhai@intel.com> Signed-off-by: Jesse Brandeburg <jesse.brandeburg@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> |
