[mythtv-users] Ceton InfiniTV PCIe Driver Compilation Error

[Scott Knight]

Hello All,

At my wit's end with this thing and not sure where to turn.  The driver 
is "provided without warranty or support" and has worked very well all 
these years (released in 2013) with only a single easily fixed tweak a 
couple of years ago for kernel 2.6.8 or 2.6.9.  A few months ago, it 
quit compiling on my FC25 backend and I have been occasionally searching 
to see if anyone mentioned fixing it.  The last kernel it compiles 
cleanly with is 4.11.4, so I have been holding tight on that.  Now with 
FC27 released, things are a little more urgent since FC25 will be 
getting dropped pretty soon.

I was able to easily fix the two implicit declaration of function errors 
myself with a quick search, but these two (which really look like the 
same thing twice) have me stumped.  Surely, it's very easy for someone 
familiar enough with C and device drivers but sadly, I am neither.  Here 
is the error:


/root/ceton/ceton_infinitv_linux_driver_2013_0326_2226/ctn91xx_net.c: In 
function ‘ctn91xx_net_rx_skb’:
/root/ceton/ceton_infinitv_linux_driver_2013_0326_2226/ctn91xx_net.c:315:11: 
error: ‘struct net_device’ has no member named ‘last_rx’
      netdev->last_rx = jiffies;
            ^~

                  netdev->last_rx = jiffies;
                        ^~

Anyone interested in helping me tackle this?  I cannot imagine the list 
handling an attachment, so would either need to paste relevant parts of 
code here or work off to the side in private email?

Thank you, Scott
