Yep I noted the deprecation of the e1000 driver in my Gateway Performance Optimization Course on the page shown below.  There will also be a major jump in all NIC driver versions due to the new 4.10.0-372.9 kernel that may cause behavioral changes at the network level.

Also a new R82 tool called connview that allows the easy viewing of connection attributes such as what processing path they are in, why they are slowpath, etc.  This replaces the jumble of different commands used to determine this information in R81.20 and earlier such as fw ctl multik gconn, fwaccel conns, fw tab -t connections -z, fw_mux, fw_streaming, etc.  I attached the relevant page for that too.  A few other tidbits I'm excited about in R82:

1) The much more efficient Galois Counter Mode (GCM) AES algorithms are now available for IKE Phase 1, not just Phase 2/IPSec.  Also a new enhanced VPN Monitoring Tool to replace the SmartView Monitor status screens.

2) Hyperflow/pipelining  can boost CIFS/SMB connections

3) A new implementation of the gateway logging mechanism that is multi-threaded (no more legacy fwd log bottlenecks).

4) R77.30 is no longer supported for backward management compatibility with gateways!
