parentnet: dsa: use cpu_switch instead of ds[0] (diff)
net: Remove usage of net_device last_rx member
The network stack no longer uses the last_rx member of struct net_device since the bonding driver switched to use its own private last_rx in commit 9f242738376d ("bonding: use last_arp_rx in slave_last_rx()"). However, some drivers still (ab)use the field for their own purposes and some driver just update it without actually using it. Previously, there was an accompanying comment for the last_rx member added in commit 4dc89133f49b ("net: add a comment on netdev->last_rx") which asked drivers not to update is, unless really needed. However, this commend was removed in commit f8ff080dacec ("bonding: remove useless updating of slave->dev->last_rx"), so some drivers added later on still did update last_rx. Remove all usage of last_rx and switch three drivers (sky2, atp and smc91c92_cs) which actually read and write it to use their own private copy in netdev_priv. Compile-tested with allyesconfig and allmodconfig on x86 and arm.
