It is a bit strange to see something as specific as Broadcom SYSTEMPORT
bits in the main DSA include file. Move these away into a separate
header, and have the tagger and the SYSTEMPORT driver include them.

Upon a quick inspection, it seems that there is some code in the generic
DSA layer that is somehow specific to the Broadcom SYSTEMPORT driver.
The challenge there is that the hardware integration is very tight between
the switch and the DSA master interface. However this does not mean that

Add two sets of BPF_CORE_READ()-like macros. One is for reading kernel data
from user address space (e.g., UAPI data structs for syscalls). Another one is
non-CO-RE variants, which don't emit CO-RE relocations and thus won't fail on
kernels without BTF. The latter one still provides much shorter wa
BPF_CORE_READ(), in addition to handling CO-RE relocations, also allows much

a sequence of bpf_probe_read() calls to follow links, one can just write

Add BPF_CORE_READ_USER(), BPF_CORE_READ_USER_STR() and their _INTO()
variations to allow reading CO-RE-relocatable kernel data structures from the
