From 2e56fbc87f6ec3cd56c37b01d313abd502b80d61 Mon Sep 17 00:00:00 2001 From: Peter Lieven Date: Thu, 4 Apr 2019 14:10:15 +0200 Subject: megasas: fix mapped frame size the current value of 1024 bytes (16 * MFI_FRAME_SIZE) we map is not enough to hold the maximum number of scatter gather elements we advertise. We actually need a maximum of 2048 bytes. This is 128 max sg elements * 16 bytes (sizeof (union mfi_sgl)).
