The number of words that the read FIFO has to contain except the end of frame before sends data back to the host. Max watermark = (512B - 2* (BurstLength))/4 = (512 - 128)/4 = 384/4 = 0x60 so if burst length (i.e. BurstLength = 64) is increased, watermark has to be reduced. This is the optimal setting for this chip. Reviewed-by:

The credit numbers are static and tunable per chip in firmware side. However the credit number may be changed that is based on packet pool length and will send BRCMF_E_FIFO_CREDIT_MAP event to notify host driver updates the credit numbers during interface up.

Comparing the existing TX_BITRATE parsing code (in mwifiex_parse_htinfo()) with the RX bitrate histograms in debugfs.c, it appears that the rxpd_rate and rxpd_htinfo fields have the same format. At least, they give reasonable results when I parse them this way. So this patch adds support for RX_BITRATE to our station info dump. Along the way, I add legacy bitrate parsing into the same function, using the debugfs code (mwifiex_histogram_read() and mwifiex_adjust_data_rate()) as reference. Additionally, to satisfy the requirements of NL80211_STA_INFO_RX_BITRATE, I skip logging the bitrate of multicast packets. This shouldn't add a lot of overhead to the RX path, as there are already several similar 802.3 header checks in this same codepath. We can also bias the branch behavior to favor unicast, as that's the common performance-sensitive case. I'd consider this support somewhat experimental, as I have zero documentation from Marvell. But the existing driver code gives me good reason to think this is correct. I've tested this on a few different 802.11{a,b,g,n,ac} networks, and the reported bitrates look good to me.

There are two defects: (1) passing a NULL bss to mwifiex_save_hidden_ssid_channels will result in NULL dereference, (2) using bss after dropping the reference to it via cfg80211_put_bss. To fix them, the patch moves the buggy code to the branch that bss is not NULL and puts it before cfg80211_put_bss. Signed-off-by:

The following set of NPC registers allow the driver to configure NPC to generate different key value schemes to compare against packet payload in MCAM search. NPC_AF_INTF(0..1)_KEX_CFG NPC_AF_KEX_LDATA(0..1)_FLAGS_CFG NPC_AF_INTF(0..1)_LID(0..7)_LT(0..15)_LD(0..1)_CFG NPC_AF_INTF(0..1)_LDATA(0..1)_FLAGS(0..15)_CFG Currently, the AF driver populates these registers to configure the default values to address the most common use cases such as key generation for channel number + DMAC. The secure firmware stores different configuration value of these registers to enable different NPC use case along with the name for the lookup. Patch loads profile binary from secure firmware over the exiting CGX mailbox interface and apply the profile. AF driver shall fall back to the default configuration in case of any errors. The AF consumer driver can know the selected profile on response to NPC_GET_KEX_CFG mailbox by introducing mkex_pfl_name in the struct npc_get_kex_cfg_rsp. Signed-off-by:

TL1 is the root node in the scheduling hierarchy and it is a global resource with a limited number. This patch introduces restriction and validation on the allocation of the TL1 nodes for the effective resource sharing across the AF consumers. - Limit TL1 allocation to 2 per lmac. One could be for the normal link and one for IEEE802.3br express link (Express Send DMA). Effectively all the VF's of an RVU PF(lmac) share the two TL1 schqs. - TL1 cannot be freed once allocated. - Allow VF's to only apply default config to TL1 if not already applied. PF's can always overwrite the TL1 config. - Consider NIX_AQ_INSTOP_WRITE while validating txschq when sq.ena is set. Signed-off-by:

On AF driver init, it would reserve a predefined set RSS algo indexes, which will be available all the time for all the AF driver consumers. The leftover algo indexes can be reserved at runtime through exiting nix_rss_flowkey_cfg mailbox message.
