Revision e488921f44765e8ab6c48ca35e3f6b78df9819df authored by Michal Schmidt on 13 September 2012, 12:59:44 UTC, committed by David S. Miller on 18 September 2012, 20:13:46 UTC
Commit d6cb3e41 "bnx2x: fix checksum validation" caused a performance regression for IPv6. Rx checksum offload does not work. IPv6 packets are passed to the stack with CHECKSUM_NONE. The hardware obviously cannot perform IP checksum validation for IPv6, because there is no checksum in the IPv6 header. This should not prevent us from setting CHECKSUM_UNNECESSARY. Tested on BCM57711. Signed-off-by: Michal Schmidt <mschmidt@redhat.com> Acked-by: Eric Dumazet <edumazet@google.com> Acked-by: Eilon Greenstein <eilong@broadcom.com> Signed-off-by: David S.

Say yes if you want PN544 Near Field Communication driver.
This is for i2c connected version. If unsure, say N here.
To compile this driver as a module, choose m here. The module will
be called pn544.

---help---
NXP PN544 i2c driver.
This is a driver based on the SHDLC and HCI NFC kernel layers and
will thus not work with NXP libnfc library.
To compile this driver as a module, choose m here. The module will
be called pn544_hci.
config NFC_PN533

depends on USB
help
NXP PN533 USB driver.
This driver provides support for NFC NXP PN533 devices.
Say Y here to compile support for PN533 devices into the
kernel or say M to compile it as module (pn533).
config NFC_WILINK
tristate "Texas Instruments NFC WiLink driver"
depends on TI_ST && NFC_NCI
help
This enables the NFC driver for Texas Instrument's BT/FM/GPS/NFC
combo devices. This makes use of shared transport line discipline
core driver to communicate with the NFC core of the combo chip.
Say Y here to compile support for Texas Instrument's NFC WiLink driver
into the kernel or say M to compile it as module.
