Subject: [PATCH 010/189] net/hns3: fix jumbo frame flag condition for MTU set
|
|
|
|
The jumbo frame uses the 'RTE_ETHER_MAX_LEN' as boundary condition,
|
|
but the Ether overhead is larger than 18 when it supports dual VLAN tags.
|
|
That will cause the jumbo flag rx offload is wrong when MTU size is
|
|
'RTE_ETHER_MTU'.
|
|
|
|
This fix will change the boundary condition with 'HSN3_DEFAULT_FRAME_LEN',
|
|
that perhaps impacts the cases of the jumbo frame related.
|
|
|
|
Fixes: 1f5ca0b460cd ("net/hns3: support some device operations")
|
|
Fixes: a5475d61fa34 ("net/hns3: support VF")
