This mechanism reduces the numbers of false alram in cck rate by dynamically adjusting the value of power threshold and cs_ratio. We determine the new value by three factors, which are rssi, false alarm count and igi. Based on these factors, we define the current condition into five levels. Compared to the previous level, if the level is changed, we set the new values for power threshold and cs_ratio. Signed-off-by:

Since 8822c requires to do not only IQK, but also DPK. Move these calibrations that need to be done once the channel is determined, into phy_calibration. And note that the order of the calibrations matters, 8822c should do IQK first, then DPK. Signed-off-by:

Tzu-En Huang authored
Power amplifiers are not linear components, and require DPK to reduce its nonlinearity. DPK is called Digital Pre-distortion Calibration, can be used to compensate the output of power. DPK tracking is in charge of tracking the thermal changes. And it then shifts the power curve accordingly, which makes the power output remains linear even if the PA works in different temperature. To perform DPK, the parameter table should also be updated. And the table will be applied when device is powered on. Then DPK will reference the values to calibrate. Signed-off-by:

Add support for doing IQK in firmware Ideally the RF component's I/Q vectors should be orthogonal, but usually they are not. So we need to calibrate for the RF components, ex. PA/LNA, ADC/DAC. And if the I/Q vectors are more orthogonal, the mixed signal will have less deviation. This helps with those rates with higher modulation (MCS8-9), because they have more strict EVM/SNR requirement. Also the better of the quality of the signal, the longer it can propagate, and the better throughput performance we can get. Signed-off-by:

rtlwifi: rtl8188ee: rtl8192ce: rtl8192de: rtl8723ae: rtl8821ae: Remove some unused bit manipulation macros Each of these drivers defines some device to host macros that are never used, thus they can be removed. Signed-off-by:

In this step, the read/write routines for the descriptors are converted to use __le32 quantities, thus a lot of casts can be removed. Callback routines still use the 8-bit arrays, but these are changed within the specified routine. The macro that cleared a descriptor has now been converted into an inline routine. Signed-off-by:

Larry Finger authored
As a first step in the conversion, the macros that set the RX and TX descriptors are converted to static inline routines, and the names are changed from upper to lower case. To minimize the changes in a given step, the input descriptor information is left as as a byte array (u8 *), even though it should be a little-endian word array (__le32 *). That will be changed in the next patch. Several places where checkpatch.pl complains about a space after a cast are fixed. Signed-off-by:

This driver uses a set of local macros to manipulate the RX and TX descriptors, which are all little-endian quantities. These macros are replaced by the bitfield macros le32p_replace_bits() and le32_get_bits(). In several places, the macros operated on an entire 32-bit word. In these cases, a direct read or replacement is used. Signed-off-by:

This moves "ops" pointer from "struct brcmf_cfg80211_info" to the "struct brcmf_pub". This movement makes it possible to allocate wiphy without attaching cfg80211 (brcmf_cfg80211_attach()). It's required for later separation of wiphy allocation and driver initialization. While at it fix also an unlikely memory leak in the brcmf_attach(). Signed-off-by:

It now works as similarly to the ksz9477 SPI driver as possible, using the same regmap macros. Add support for ksz9567 to the ksz9477 driver (tested on a board with ksz9567 connected via I2C).

When tcp sends a TSO packet, adding a PSH flag on it reduces the sojourn time of GRO packet in GRO receivers. This is particularly the case under pressure, since RX queues receive packets for many concurrent flows. A sender can give a hint to GRO engines when it is appropriate to flush a super-packet, especially when pacing is in the picture, since next packet is probably delayed by one ms. Having less packets in GRO engine reduces chance of LRU eviction or inflated RTT, and reduces GRO cost. We found recently that we must not set the PSH flag on individual full-size MSS segments [1] : Under pressure (CWR state), we better let the packet sit for a small delay (depending on NAPI logic) so that the ACK packet is delayed, and thus next packet we send is also delayed a bit. Eventually the bottleneck queue can be drained. DCTCP flows with CWND=1 have demonstrated the issue. This patch allows to slowdown the aggregate traffic without involving high resolution timers on senders and/or receivers. It has been used at Google for about four years, and has been discussed at various networking conferences. [1] segments smaller than MSS already have PSH flag set by tcp_sendmsg() / tcp_mark_push(), unless MSG_MORE has been requested by the user.

This is the equivalent of commit 2c6b55f4 ("ipv6: fix neighbour resolution with raw socket") for ip6_confirm_neigh(): we can send a packet with MSG_CONFIRM on a raw socket for a connected route, so the gateway would be :: here, and we should pick the next hop using rt6_nexthop() instead. This was found by code review and, to the best of my knowledge, doesn't actually fix a practical issue: the destination address from the packet is not considered while confirming a neighbour, as ip6_confirm_neigh() calls choose_neigh_daddr() without passing the packet, so there are no similar issues as the one fixed by said commit. A possible source of issues with the existing implementation might come from the fact that, if we have a cached dst, we won't consider it, while rt6_nexthop() takes care of that. I might just not be creative enough to find a practical problem here: the only way to affect this with cached routes is to have one coming from an ICMPv6 redirect, but if the next hop is a directly connected host, there should be no topology for which a redirect applies here, and tests with redirected routes show no differences for MSG_CONFIRM (and MSG_PROBE) packets on raw sockets destined to a directly connected host. However, directly using the dst gateway here is not consistent anymore with neighbour resolution, and, in general, as we want the next hop, using rt6_nexthop() looks like the only sane way to fetch it.

Alexandru Ardelean authored
In-between the MAC & PHY there can be a mode converter, which converts one mode to another (e.g. GMII-to-RGMII). The converter, can be passive (i.e. no driver or OS/SW information required), so the MAC & PHY need to be configured differently. For the `stmmac` driver, this is implemented via a `mac-mode` property in the device-tree, which configures the MAC into a certain mode, and for the PHY a `phy_interface` field will hold the mode of the PHY. The mode of the PHY will be passed to the PHY and from there-on it work in a different mode. If unspecified, the default `phy-mode` will be used for both. Signed-off-by:
