One possible cause of packet drops is when softirqs are disabled for too
long periods, even if NIC has a big RX ring (check ethtool -g eth0)

Why aren't the softirqs converted to workqueues? Wouldn't that cut 
dependencies to other softirq users and improve latency?

Because it was done like that in the old days.

Its a bit less important these days, now typical machines have 8+ cpus.
Each device interrupt can be handled by its own cpu :)
