kernel configuration as well as patches for Linux 5.4.
There were no targets still actively using Linux 5.4.

-Subject: [PATCH] sdk_dpaa: ls1043a errata: restrict the max mtu
-
-We can not allow for Jumbo frames and large MTU values on LS1043A due to
-the A-010022 FMan errata. All outgoing frames larger than 4K bytes are dropped.
