[v2,net-next,0/2] Enable Big TCP for MANA devices

Message

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 v2
 * Instead of using 'tcp segment' throughout the patch used the words
   'aggregated pkt size'

  net: mana: Allow tso_max_size to go up-to GSO_MAX_SIZE in MANA
  hv_netvsc: Use VF's tso_max_size value when data path is VF
