Subject: scsi: lpfc: Correct BDE DMA address assignment for GEN_REQ_WQE
Patch-mainline: v5.18-rc7
Git-commit: 7752662071053adcdb6b6e7853834205dd60e1c0
References: bsc#1200045

Garbage FCoE CT frames are transmitted on the wire because of bad DMA ptr
addresses filled in the GEN_REQ_WQE.

The __lpfc_sli_prep_gen_req_s4() routine is using the wrong buffer for the
payload address. Change the DMA buffer assignment from the bmp buffer to
the bpl buffer.
