Subject: [PATCH v2 net-next 0/2] Enable Big TCP for MANA devices
Date: Sun, 9 Feb 2025 20:39:52 -0800 [thread overview]
Message-ID: <1739162392-6356-1-git-send-email-shradhagupta@linux.microsoft.com> (raw)
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'
Shradha Gupta (2):
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
