net: ipa: add IPA v5.1 and v5.5 to ipa_version_string()

2025-08-15T10:14:05+00:00

[ Upstream commit f2aa00e4f65efcf25ff6bc8198e21f031e7b9b1b ] Handle the case for v5.1 and v5.5 instead of returning "0.0". Also reword the comment below since I don't see any evidence of such a check happening, and - since 5.5 has been missing - can happen.

net: ipa: Enable checksum for IPA_ENDPOINT_AP_MODEM_{RX,TX} for v4.7

2025-03-13T12:02:07+00:00

[ Upstream commit 934e69669e32eb653234898424ae007bae2f636e ] Enable the checksum option for these two endpoints in order to allow mobile data to actually work. Without this, no packets seem to make it through the IPA.

net: ipa: allocate dummy net_device dynamically

2024-04-24T11:00:16+00:00

Embedding net_device into structures prohibits the usage of flexible arrays in the net_device structure. For more details, see the discussion at [1]. Un-embed the net_device from the private struct by converting it into a pointer. Then use the leverage the new alloc_netdev_dummy() helper to allocate and initialize dummy devices.

net: ipa: kill ipa_version_supported()

2024-04-23T11:08:08+00:00

The only place ipa_version_supported() is called is in the probe function. The version comes from the match data. Rather than checking the version validity separately, just consider anything that has match data to be supported. Signed-off-by: Alex Elder Signed-off-by: Paolo Abeni

net: ipa: fix two minor ipa_cmd problems

2024-04-23T11:08:08+00:00

In "ipa_cmd.h", ipa_cmd_data_valid() is declared, but that function does not exist. So delete that declaration. Also, for some reason ipa_cmd_init() never gets called. It isn't really critical--it just validates that some memory offsets and a size can be represented in some register fields, and they won't fail with current data. Regardless, call the function in ipa_probe(). Signed-off-by: Alex Elder Signed-off-by: Paolo Abeni

net: ipa: make ipa_table_hash_support() a real function

2024-04-23T11:08:08+00:00

With the exception of ipa_table_hash_support(), nothing defined in "ipa_table.h" requires the full definition of the IPA structure. Change that function to be a "real" function rather than an inline, to avoid requring the IPA structure to be defined. Signed-off-by: Alex Elder Signed-off-by: Paolo Abeni
