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 
bnx2x: fix rx checksum validation for IPv6
 
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.

	  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.

	  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

	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.
