Subject: [PATCH] scsi: lpfc: Fix link speed reporting for 4-link trunk
References: bsc#1136217,jsc#SLE-4722
Git-commit: f3339800f98c30bcca1b70e4201f38b41d4926b1
Patch-mainline: v5.2-rc1
Driver is using uint16_t and is encountering an overflow of the 16bits when
calculating link speed.
Fix by using a u32 type.
