* kernel: add IEEE-1284 parallel port supportDaniel Gimpelevich2018-02-121-5/+40
| | | | | | | | | | The kmod-lp package included both lp.ko and ppdev.ko, but ECP device drivers may or may not require lp NOT to be loaded, needing only ppdev. Additionally, There were no packages for any parport interface modules, such as uss720 or parport_pc, provided here. It has not been otherwise possible to use PC-style parport hardware for kmod-lp.

* kernel: add kmod-fouFilip Moc2018-02-101-0/+22
| | | | | | | | | Once installed fou kernel module allows you to use FOU (Foo over UDP) and GUE (Generic UDP encapsulation) tunnel protocols. To get ip fou command working you also need to install ip-full. Signed-off-by: Filip Moc <lede@moc6.cz>

* netfilter: clean up dependencies of kernel modulesMatthias Schiffer2018-01-311-15/+38
| | | | | | | | | The nf_reject_ipv4 and nf_reject_ipv6 modules are moved into separate packages, as they are a common dependency of ip(6)tables and nftables. This avoids a dependency of nftables on kmod-nf-ipt(6). Also, fewer iptables modules depend on nf-conntrack(6) now. Signed-off-by: Matthias Schiffer <mschiffer@universe-factory.net>

* kernel: fix packaging of kmod-gpio-nxp-74hc164Jo-Philipp Wich2018-01-071-3/+3
| | | | | | | | | | | | | | | | The NXP 74HC164 GPIO expander driver uses a different config symbol ("CONFIG_GPIO_74X164") and module name since since at least Kernel version 2.6.37. Update the kmod package definition accordingly by adjusting kconfig and module file names. This unrelated, but correct change has been separated from the WNR2000v5 support commits.

* kernel: make uas work during early bootDaniel Albers2018-01-021-1/+1
| | | | | | | | | | | | Add the uas(p) module to the modules loaded early on the boot process. The uas(p) is an modern alternative, which is used by the modern USB3 storage cases, compared to the bot protocol. To be able to use uas(p) storage cases for extroot, the kernel module has to be loaded before the search for extroot has been called. This patch changes the load order to support uas(p) storage cases for extroot. Signed-off-by: Daniel Albers <daniel.albers@public-files.de>

| | | | | | | | | | In kernel 4.14 kmod-bluetooth depends on kmod-crypto-ecdh, add kmod-crypto-ecdh to LEDE. Both packages also depend on the kmod-crypto-kpp package. To build this we have to fix the dependency of CRYPTO_ECDH which has a typo. This patch is already accepted upstream. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>

* kernel: tune e1000e module parametersJo-Philipp Wich2017-12-161-0/+3
| | | | | | | | | | | | | The default e1000e parameters (interrupt throttling rate, MSI/MSI-X mode) are optimized for desktop and server computers to optimize user-space execution (i.e. what's typically referred to as "useful" work). This assumption breaks on a router under load where most of the "useful" work actually takes place either in hardware interrupt handlers (IRQ) or at software IRQ (swirq) modes, so we try to reflect that by overriding these parameters with more appropriate values.

* kernel: add NFS4 client supportMarcin Jurkowski2017-11-222-17/+68
| | | | | | | | | | | | | | | | | | | Adds NFS4 client support: 1. Package kmod-fs-nfs is split into kmod-fs-nfs (nfs.ko) and kmod-fs-nfs-v3 (nfsv3.ko). 2. A new package kmod-fs-nfs-v4 (nfsv4.ko) is created. 3. Package kmod-fs-nfs-common-v4 is renamed to kmod-fs-nfs-rpcsec and includes additional module rpcsec_gss_krb5.ko. CONFIG_NFS_V4 goes into kmod-fs-nfs-v4, CONFIG_NFSD_V4 (NFS4 server) is removed. Missing kernel module oid_registry.ko needed by auth_rpcgss.ko is added to the package. A new package kmod-crypto-cts needed by rpcsec_gss_krb5.ko is also created.
