I got it working, and confirmed the bug, only problem is it will get
overwritten with the next patch, and others cant use the fix.
Hopefully this is a quick fix for a proc dev.
This is how i did it
When you try to compile the drivers you get
./r8152-2.15.0/r8152.c:18530:25: error: initialization of ‘int (*)(struct
net_device *, struct ethtool_coalesce *, struct kernel_ethtool_coalesce *,
struct netlink_ext_ack *)’ from incompatible pointer type ‘int (*)(struct
net_device *, struct ethtool_coalesce *)’ [-Werror=incompatible-pointer-types]
18530 | .get_coalesce = rtl8152_get_coalesce,
| ^~~~~~~~~~~~~~~~~~~~
./r8152-2.15.0/r8152.c:18530:25: note: (near initialization for
‘ops.get_coalesce’)
./r8152-2.15.0/r8152.c:18531:25: error: initialization of ‘int (*)(struct
net_device *, struct ethtool_coalesce *, struct kernel_ethtool_coalesce *,
struct netlink_ext_ack *)’ from incompatible pointer type ‘int (*)(struct
net_device *, struct ethtool_coalesce *)’ [-Werror=incompatible-pointer-types]
18531 | .set_coalesce = rtl8152_set_coalesce,
I had a look at the code and googled (i cant code in C or C++ btw)
This site had similar code
https://sbexr.rabexc.org/latest/sources/26/53bfa290b96570.html#0000e00100031001
so i made the following changes to the realtek code. not sure if it
right or performant, but it now compiles
# diff ./r8152.c ../r8152-2.15.0/r8152.c
18339,18341c18339
< struct ethtool_coalesce *coalesce,
< struct kernel_ethtool_coalesce *,
< struct netlink_ext_ack *)

> struct ethtool_coalesce *coalesce)
18360,18363c18358
< struct ethtool_coalesce *coalesce,
< struct kernel_ethtool_coalesce *,
< struct netlink_ext_ack *)
<
---
> struct ethtool_coalesce *coalesce)
make install copied the code , but throws the following error, looks to
do with code signing ??? Any way i ignored it
At main.c:160:
- SSL error:02001002:system library:fopen:No such file or directory:
../crypto/bio/bss_file.c:69
- SSL error:2006D080:BIO routines:BIO_new_file:no such file:

sign-file: certs/signing_key.pem: No such file or directory
I ran
# sudo depmod -a
# sudo update-initramfs -u
as requested by the drivers readme file
rebooted
ethtool -s enx5c857e38e9b7 autoneg on advertise 0x80000000002f
now works
