Once udp stack has set the UDP_SKB_IS_STATELESS flag, later skb free assumes all skb head state has been dropped already. This will leak the extension memory in case the skb has extensions other than the ipsec secpath, e.g. bridge nf data. To fix this, set the UDP_SKB_IS_STATELESS flag only if we don't have extensions or if the extension space can be free'd.

tristate "Non-Transparent Bridge support"
depends on PCI
help
The PCI-E Non-transparent bridge hardware is a point-to-point PCI-E bus
connecting 2 systems. When configured, writes to the device's PCI
mapped memory will be mirrored to a buffer on the remote system. The
ntb Linux driver uses this point-to-point communication as a method to
transfer data from one system to the other.
If unsure, say N.

bool "MSI Interrupt Support"
depends on PCI_MSI
help
Support using MSI interrupt forwarding instead of (or in addition to)
hardware doorbells. MSI interrupts typically offer lower latency
than doorbells and more MSI interrupts can be made available to
clients. However this requires an extra memory window and support
in the hardware driver for creating the MSI interrupts.
If unsure, say N.

help
This is a transport driver that enables connected systems to exchange
messages over the ntb hardware. The transport exposes a queue pair api
to client drivers.
