Merge branch 'net-mana-big-tcp'

Shradha Gupta says:

====================
net: Enable Big TCP for MANA devices

Allow the max gso/gro aggregated pkt size to go up to GSO_MAX_SIZE for
MANA NIC. On Azure, this not possible without allowing the same for
netvsc NIC (as the NICs are bonded together).
Therefore, we use netif_set_tso_max_size() to set max aggregated pkt
size
to VF's tso_max_size for netvsc too, when the data path is switched over
to the VF

The first patch allows MANA to configure aggregated pkt size of up-to
GSO_MAX_SIZE

The second patch enables the same on the netvsc NIC, if the data path
for the bonded NIC is switched to the VF

---
 Changes in v3
 * Add ipv6_hopopt_jumbo_remove() while sending Big TCP packets
---
  Changes in v2
  * Instead of using 'tcp segment' throughout the patch used the words
    'aggregated pkt size'
