Hi @Dimka88! The warnings are fixed in the following pull request:
https://github.com/accel-ppp/accel-ppp/pull/64
From my understanding, the situation is next:

In general, assuming anything about data alignment is a bad practice that leads to very obscure errors. 
Taking the address of a packed member is dangerous since the reduced alignment of the pointee is lost.
If the pointer value is dereferenced, this can lead to memory alignment faults in some architectures.

1. IPoE.  We need to guarantee 2-byte alignment for the `hdr` pointer in `ip_csum(uint16_t *buf, ...)` calculation
      664 |  hdr->ip.check = ip_csum((uint16_t *)&hdr->ip, sizeof(hdr->ip));
          |                                      ^~~~~~~~

   I expected this cast to have no side effects. Local/stack variables are typically aligned based on their natural size.
   In that case, accessing `(uint16_t *)&hdr->ip` would result in aligned 2-byte access starting at `&hdr + 16 (sizeof ether_header)`

   However, it looks like stack alignment is not guaranteed for the packed structures.
   Therefore, we need to explicitly specify the `__aligned(2)` attribute.

2. PPPOE: Suppress false-positive warning for `sockaddr_pppox.`
   Similar issue: https://github.com/kernelslacker/trinity/pull/40
   Looking through the kernel code involving this structure, I can see no special handling.
   I assume the compiler warns about alignment between `const/non const` types (??)
   https://gcc.gnu.org/onlinedocs/gcc/Diagnostic-Pragmas.html

3. Introduce tmp variables to avoid alignment issues for SSTP/DHCPv6

Source file was:

#include <linux/if_link.h>
int main(void)
{
	return IFLA_VRF_UNSPEC+IFLA_VRF_TABLE;
}

UPD:// CMake Error looks pretty strange. It get info by the command git describe --tags --always
From your repo it return 6e5f998 because you clone only single branch.

root@debian11:/opt/accel-ppp/build# git describe --tags --always
6e5f998

So, maybe we have to improve generate version functionality also
