There was a previous attempt to use xmit_more, but the change had to be reverted because under load sometimes a transmit timeout occurred [0]. Maybe this was caused by a missing memory barrier, the new attempt keeps the memory barrier before the call to netif_stop_queue like it is used by the driver as of today. The new attempt also changes the order of some calls as suggested by Eric. [0] https://lkml.org/lkml/2019/2/10/39Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: David S.

Andy Shevchenko says: ==================== NFC: nxp-nci: clean up and new device support Few people reported that some laptops are coming with new ACPI ID for the devices should be supported by nxp-nci driver. This series adds new ID (patch 2), cleans up the driver from legacy platform data and unifies GPIO request for Device Tree and ACPI (patches 3-6), removes dead or unneeded code (patches 7, 9, 11), constifies ID table (patch 8), removes comma in terminator line for better maintenance (patch 10) and rectifies Kconfig entry (patches 12-14). It also contains a fix for NFC subsystem as suggested by Sedat. Series has been tested by Sedat. Changelog v4: - rebased on top of latest linux-next - appended cover letter - elaborated removal of pr_fmt() in the patch 11 (David) ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

This patch clarifies on the supported NXP NCI chips and families and lists PN547 and PN548 separately which are known as NPC100 respectively NPC300. This helps to find informations and identify drivers on vendor's support websites. For details see the discussion in [1] and [2].

The macro had never been used. The driver uses mostly the nfc_err(), which, with other macros in the family, is backed by corresponding dev_err(). pr_fmt() is not used for dev_err() macro. Moreover, there is no need to print the module name which is part of the device instance name anyway.

Hardware supports 0.5K, 1K, 2K, 4K RX buffer size, the RX buffer can not be reused because the hns3_page_order return 0 when page size and RX buffer size are both 4096. So this patch changes the hns3_page_order to return 1 when RX buffer is greater than half of the page size and page size is less the 8192, and dev_alloc_pages has already been used to allocate the compound page for RX buffer. This patch also changes hnae3_* to hns3_* for page order and RX buffer size calculation because they are used in hns3 module.
